This article series describes and illustrates antique & modern hardware: door knobs, latches, hinges, window latches, hardware, nails & screws can help determine a building's age by noting how those parts were fabricated: by hand, by machine, by later generations of machine.

Railroad Spikes: history, identification, age, uses

1832 - Present: Cut Spikes, Railroad Spikes & Offset Head Nails

In our images above and also in Alyssa's railroad spike photos shown here you'll notice that the head of these large railroad spikes sport an offset head.

[Click to enlarge any image]

The larger lip of the offset head on these large spikes, also called crampons, was used to secure the bottom edge of the rail to the steel plate upon which the rail rests.

As the railroad spike is driven through the plate and onwards into the railroad tie or (sleeper), the combination of spike, tie-plate, and sleeper hold the rail in place in the stone-covered bed (ballast) of the railway.

Invention of the railroad spike is credited to Robert Livingston Stevens, president of the Camden & Amboy Railroad, and first used in the U.S. in 1832. (Wikipedia). Stevens is also credited with invention of the T-shaped rail on which rail cars run.

However a patent for railroad spikes search finds slightly-later dates and inventors for citation, as we illustrate below.

Photos above and below: traditional railroad spikes in-use - from http://www.rail-fastener.com/agico-railroad-spikes.html

In the U.S. the transcontinental railroad was completed on May 10, 1869 when the last spike, "the golden spike", was driven into a tie at Promtory Summit, Utah.

Early Railroad Spike Patent History: 1834 & Later

The earliest railroad of any form in the U.S. was constructed in 1764 for military purposes at the Niagara portage in Lewiston, New York. - (LOC)

The first actual charter for a railroad in the United States was granted to Stevens in 1815, but surveying and construction on the first U.S. railroad, the Baltimore and Ohio, chartered in 1827, didn't really begin operation until 1830 when the first fourteen miles of track were completed. (Library of Congress, cited below).

Railroad spikes may have been hand-forded in small quantity, but almost immediately the need for railway spike producing machines would have been evident.

So although you might expect to find a railroad spike that's hand forged but in our opinion that'd be uncommon.

Consider that by the time railroads were being built across the U.S. Continent the volume of spikes needed to secure rails to ties was so enormous that hand-forging these fasteners would not have been reasonable.

But those off-set or "hook-headed" spikes may date from about 1850.

  This invention relates to railroads and more particularly to rail fastening means, and has for its object to provide a fastening means of this character including a spike having a main shank and a supplemental shank so arranged that the supplemental shank will be brought into engagement with a portion of the main shank when driven into material, thus anchoring the spike and preventing its disengagement.
  ...
  When the spike is driven home, the engagement of the bevel face 9 with the material of the tie will cause the shank 6 to bend 50 laterally in the direction of the rail, and the face 11 of the supplemental shank 10, com ing into engagement with the material of the tie, will cause this shank 10 to bend in the same direction.
  
  By reason of the fact that the shank 10 is thinner than the shank 6, as shown in the drawings, the bending of the shank 10 is more abrupt than that of the shank 6, and consequently the lower end of with the rearward face of the shank 6, the spike. being thus securely locked in the tie.

  Excerpt:
  The determination of a proper fastening between the rail and the tie has become a matter of considerable importance. Duringthe period when the supply of suitable hard wood timber was sufficient, the ordinary spike satisfactorily fulfilled the requirements of traffic; but with the increase in the amount of trafiic handled, and the heavier weights of cars and locomotives, and also with the use of soft deciduous and coniferous woods for ties, the common spike has proved deficient.
  
  Variations in the formof the ordinary spike have been developed, and new forms of spikes have been devised in an attempt to overcome the loss of efficiency attendant upon the use of inferior timbers.
  
  In view of these conditions, and the meager supply of published data on the holding power of spikes in ties, the writer has carried out a series of experiments to determine the resistance to withdrawal offered by the same type of spike in different timbers and by different forms of spikes in the same timber, and also to determine whether or not the preservative has any influence upon this resistance.

Date Nails Used in Dating Railroad Ties Help Identify Railroad Spikes & Spike Age

Illustration: hand-hewn railroad crossties cut from lodgepole pine, ca 1912 - 1913 - US Forest Service (Merritt 2016).

In the U.S. beginning in 1909 some railroads used date nails, a specially-manufactured nail that included a year encoded in the nail head, possibly also including a shape or image that identified the nail manufacturer.

So if you by slight chance and luck found an old railroad spike still in a railroad tie where such a nail is also found, that date nail will give a reasonable guess at the earliest possible age of the railroad spike itself.

We say possible date rather than definite date because you can't be certain that a given railroad spike is not a replacement.

Oaks "Date Nails" gives a nice history of the use of date nails and includes some examples of date codes for specific railroads. - retrieved 2022/12/31, original source: University of Indianapolis, 1400 East Hanna Avenue Indianapolis, Indiana 46227 Main: 317-788-3368 Web: https://uindy.edu/cas/mathematics/oaks/datenails/

General date nail age & use guidelines for railroad ties in the U.S.

• 1897 Earliest date nail use known: Mississippi River & Bonne Terre
• 1899 Most railroads began using date nails, beginning with the Chicago & Eastern IL and several others
• 1920s Most railroads were using date nails to track railroad tie condition and life
• 1930-1939 peak of date nail use in railroad ties
• 1950 - 1970 use of date nails declined
• 1971 - 2000 little or no use of date nails
• 2001 - aluminum date nail traced by George Oliva per Jeffrey Oaks
• From the 1970s to present railroads relied increasingly on stamps impressed into the ends of railroad ties to track tie life.

Other methods were also used to keep track of the age and thus monitor the condition of railroad ties such as tacking on a brass number-tag or making identifying notches or cuts into the tie itself - later leading to end-stamps or brands in railroad tie ends.

General date nail age & use in Europe

Oaks points out that lumber shortages in europe led railroads in England, France and Germany to begin treating railroad ties with chemical preservatives earlier than was done in the U.S. Date nails were in use in France possibly as early as 1859 and certainly by 1870.

  In nearly 500,000 acres stretching from the Bear River on the west to Henry’s Fork on the east, professional (full time) and subsistence or seasonal loggers harvested millions of lodgepole pines to feed the growth of the United States’ railroad infrastructure.
  
  Although the Weber and Provo headwaters and several other smaller drainages in Utah also provided ties, the North Slope of the Uintas was uniquely situated to yield a more than adequate supply.
  
  From the 1860s to the 1930s, tie cutting was completed by hand with a broad axe during the winter; the ties were floated to market using major rivers and creeks during the spring thaw, and delivered to the railroads in summer.

Excerpt:

A rail spike, also known as a cut spike or crampon, is a large nail which is used to fix rails fastening system to railroad in the track. The main function is to keep the rail in gauge.

A dog spike, also called cut track spike, is often used to fasten T-shaped railway track to wooden sleepers, to secure a rail and tie plate to the ties in track, which has a pointed penetrating head with square shank, and the underside of the spike head is sloped to compromise the top of the rail base.

At our Rail Spike Workshop Dog spikes of various sizes are available to meet the customized requirements of penetrating length of the spikes. The most popular track spikes are the 5/8” ×6” and 9/16” ×5-1/2” for smaller rail sections, especially in North America, especially US market

Question: railroad spikes marked "Gib.co" ?

2022/11/16 Sharon S

I have an old spike with ‘Gib.co.’ inscribed. .
I cannot locate info re Gib.co online.
Any info you may have

Moderator reply: GIB forces on railroad spikes & railroad tie plates

@Sharon S,

It would be most helpful if you could post a photo of your railroad spike and its marking.

Illustration above, related to railroad spikes and their history and age, is a railroad tie plate. Often the tie plates include manufacturer identification and on occasion clues to the hardware age such as a US Patent number - none of which are likely to be found on the spikes themselves.

Railroad Tie Plate, BRS Co. Pat. 1-27-2 as for sale on e-Bay in November 2022, described by the vendor as Railroad Tie Plate Vintage Blacksmith Steel Forge Anvil 9" x 8" - 7 lbs. 10 oz. possibly one of several railroad rail related patents by J.A. Byers.

We researched your question and found that the word "gib" appears (among in many other places) in railroad literature where it's used to refer in general to

A bolt or wedge made from metal [or another material] used for holding a machine [or other] part in place.

or a gib may have been used to refer also to a track plate, gib plate (railroad tie plate), or on the rail line, a railroad spike.

I've looked for a railroad spike manufacturer whose name began with "Gib" without success but that's probably what you've found.

S-marking on Railroad spikes intended for Switches

The most common marking that might be found on some railroad spikes that refers to a special railroad spike application is an “S” railroad spike.

The S was stamped into these special railroad spikes to indicate that this was an extra-strength r spike intended for use at switches where stronger lateral and dislocating forces occurred as the switch operated and then the engine and railroad cars passed over the switch.

@Nick Osborne,

And here's an interesting image from the Cheney RR spike patent:

On 2023-01-26 by InspectApedia Publisher - Cheney, Tilly, Snyder RR spike patents

@Nick Osborne,

Continuing:

Also read these relevant patents that address the problem of loosening railroad spikes or tie plates, starting with a more famous one:

Cheney, Byron M. "METHOD OF APPLYING RAILS AND TRACK SPIKE THEREFOR." [PDF] U.S. Patent 1,604,806, issued October 26, 1926.

Excerpt:
In spikes as heretofore used, when driven into the tie the head comes in contact with the top of the rail base. When the spike is driven into the tie the wood fibre on all sides of the spike shank is bent down at an angle acting as a brace to retain or hold the spike down.

As traffic moves over the track there is an upward and downward movement and to a greater or less extent a for ward movement of the rails. This movement is commonly known as wave motion.

The upward movement of the rail either re sults in the spike being pulled up or if the holding power of the tie is sufficient, in the tie moving up with the rail. When the spike is pulled it is common practice for the men to redrive them so that the head again has contact with the rail.

Due to the wave motion of the rail they are again pulled and again redriven, the result being that this alternate pulling and redriving of the spikes breaks, bends or wears off the points of the wood fibre surrounding the shank of the spike to such an extent that finally little. if any holding power is left and many spikes may be pulled with the fingers.

In time the spike hole is enlarged to such an extent that moisture readily into the heart of the tie and decay quickly follows, thus necessitating the replacement of the decayed tie.

Also the enlarging of the spike holes by the constant pulling and re-driving of the spikes permits a spread ing of the rails. Also due to the filing action of the rail as it moves up, and down throat cut spikes are quite common, that is the wearing away of the spike at the throat or just beneath the head, thus weakening the spike.

Also by driving the head down so that it comes in contact with the top of the rail base as heretofore done, the spike heads are frequently broken. This also occurs sometimes by the pulling action of the rail. Also when the spikes are pulled as stated by the waye motion of the rail, the tie plate is not held against the tie when the rail moves upwardly so there is an objec tionable rattle of the tie plates under traffic.


Tilly, Henry L. "RAILROAD PLATE WITH SPIKES." [PDF] U.S. Patent 2,417,385, issued March 11, 1947.

Excerpt:
This invention relates to improvements in a railway tie plate and spike and has for its primary object firmly to anchor a railroad rail to a cross tie and hold it against accidental displacement.

Rush, Snyder Jacob. "Fastening for rails." U.S. Patent 2,690,876, issued October 5, 1954. - this is mis-cited by Google, the proper citation would be

Snyder Jacob Rush. "FASTENING FOR RAILS." [PDF] U.S. Patent 2,690,876, issued October 5, 1954.

Excerpt:
This invention relates to rail fastenings of the kind in which a railway rail is yieldingly held against a tie plate supported on a wood tie and, as one of its objects, aims to provide an improved fastening of this kind requiring only a relatively few parts which are adapted to be economically manufactured and installed.

Another object of the present invention is to provide an improved rail fastening which, al though of a simple and inexpensive construction, Will safely hold a rail in its proper position for a prolonged period of service and in a manner which Will reduce to a minimum the longitudinal creepage of the rail and the cutting or crushing of the tie by the tie plate.

A further object is to provide an improved rail fastening of this character embodying a rail holding clamp which is connected with the tie by the use of a spike driven into a preformed bore thereof and in which the spike has increased holding power in the tie by reason of the fact that the portion of the tie Surrounding the bore has been chemically treated and hardened and such tie portion thereby rendered resistant to shearing, crushing, fraying or rotting, and also by reason of the fact that the chemical estab lishes an adhesive bond between the Spike and the tie.

On 2023-01-26 by InspectApedia Publisher - Stafford RR spike patent

@Nick Osborne,

Continuing now with what we could find about your "self-tightening" railroad spike:

Our research did not find a RxR spike with that exact property in its description, but you're dead right that the problem of loosening railroad spikes has been a concern in the railroad and track-laying industry from the outset of railroads.

A number of rail fastening system components: the rail profile, tie plate, spike, and tie, have tried to address this problem.

We found this interesting patent - a more modern one:

Stafford III, Richard J. "ACTIVE RAILROAD SPIKE AND TIE PLATE INTERCONNECTION THEREFOR." [PDF] U.S. Patent 5,024,381, issued June 18, 1991.

Abstract
A rail spike for holding a tie plate on a tie, embodied in accordance with the invention so that tie cutting is prevented, spike removal for track maintenance is facilitated, and a free rail load wave is allowed.

This preferably is attained by providing the spike with left and right side tapered shoulders and a tapered rear surface, such that a unique wedging and swaging action occurs in the tie plate hole during a final driving of the spike, limiting the depth of penetration of the spike into the tie and securely maintaining the gauge of the tie plate on the tie.

On 2023-01-24 by Nick Osborne - trying to find information on self-tightening RR spike

A Fella in Minnesota, long dead, is said to have created a RXR Spike that tightened with age to the track plate. I’ve tried to look up information and have been told there’s no such animal.

Hi, can you help me id/date these railroad spikes? They were found beside the original 1854 track going through Cary, NC (Wake County), but still used today as well. I found 3 so I will do 3 separate postings.

On 2022-11-20 by InspectApedia (Editor) - old spike with ‘Gib.co.’ inscribed

@Sharon S,

We researched Gib. Co. railroad spikes without finding the company among patents or railroad history, though we did find some clues.

I've moved your question and our detailed reply into the article above at

"Special Markings, Stamps, Logos on Railroad Spikes"

it would really be helpful if you could post a sharp photo of your Gib. Co. railroad spike showing the embossed lettering.

I have an old spike with ‘Gib.co.’ inscribed. I cannot locate info re Gib.co online. Any info you may have

@Jim,

Right, large spikes were used for a variety of purposes including Timber framing, dock construction.

On 2022-11-09 by Jim

@InspectApedia-911, This is not a nail. It is larger than a typical railroad spike. It's large. However, it doesn't have the usual lip to clamp down on the rail.

Creeps in its petty pace, from day to day...

On 2022-10-29 by InspectApedia-911 (mod) - square tapering to triangular with a point spike

@Jim Powell,

That looks like a machine made cut mail. Take a look at the nail identification articles given in the recommended articles list on this page.

Tomorrow and tomorrow and tomorrow...

On 2022-10-27 by Jim Powell

This doesn't look like a railroad spike. Does anyone know what this type of spike was used for? Square tapering to triangular with a point? Square head but not offset to catch a rail? Any help would be appreciated.

On 2022-10-19 by InspectApedia (Editor) - very early in RR history spike

@Mike,

OPINION (not researched fact) That's a very interesting RR spike - as it looks more hand-made than later rounded-headed versions that were mass-produced. Probably very early in RR history. 1860s perhaps.

On 2022-10-19 by Mike

I found the attached spike while metal detecting last week. It was between the old Santa Fe railroad and the A.V.I. Line. I assume it's an older railroad spike but, I'm not sure. Can you confirm whether it is and, what time period it would have been from? Thank you.

@davis,

Quite often holes drilled through fasteners are there to permit installing a wire to prevent the fastener from rotating and thus coming unscrewed. As we said about try the add image button. You can post one photo per comment and as many photos with comments as you like.

On 2022-10-12 by davis

@InspectApedia ,
I saved the spikes and plate today before sending the load of ties to the dump. I will fwd a photo. It is a straight wire that passes directly through holes drilled beneth the head of the spikes. The wire is straight. The plate has two holes on the side with the ridge and three holes on the inside, each off set. Will photo all.

@davis davis,

Do try to post a photo using the Add Image button so we can take a look at what you've described.

On 2022-10-11 by davis davis

Removing old retaining wall, creosoted ties, some hand hewn, one had tie plate still attached with two intact spikes. Odd, spikes are joined with a wire spring type retainer that I have never seen before.

Searching references I have not found any info about these wires- springs- clips- retainers- what are they called, who made/patented them/ dates- possible value? still in the tie today. DD

On 2022-09-14 by InspectApedia (Editor) (mod) - slotted hook on Florida coast

@Ryan,

I can't say what that larger iron item is, but you might try an image search online, as well as a second image search using an edited copy of the image that makes it symmetrical.

It looks as if it was either a slotted device that was symmetrical or a type of hook intended to hook on the side of a steel vessel, such as might have held cables or ropes used to clean the sides of a ship or an iron tank.

On 2022-09-14 by Ryan

Found these in Inverness Florida magnet fishing at and old bridge that used to be a train track but is now a bike trail. Any idea what this is? Found it magnet fishing along with a spike.

On 2022-09-12 by InspectApedia-911 (mod) - antonito rail road in colorado carriage bolt

@Jason Connell,

Top to bottom:

a rusted carriage bolt with head at right end and nut at left end

A railroad spike

A modern machine made nail

Let's get the surrounding context to put bounds on the age of railroad spike question - that's necessary because spikes were made in huge volume looking almost identical over more than 100 years now.

A quick search for "history of antonito rail road colorado" finds several websites giving history of that rail line, portions dating from 1880.

On 2022-09-12 by Jason Connell

Wondering what these might be. Found at and around antonito rail road colorado can you possibly make a educated guess as to age ?

On 2022-09-04 by InspectApedia (mod) - double headed spike

@Matt,

I certainly don't think that spike is a mistake but more likely it was made for some special purpose and certainly not intended to be used to hold Railroad rails to the ties.

More likely someone made that as an effort to demonstrate blacksmithing skills such as joining two pieces of material together. Look very closely to see if you can see a seam or joint.

Sometimes we see articles like that that are made by workers in the actual Factory where the normal product is produced. For example someone may have used a long bar of stock and simply had fun fabricating a head on both ends.

In this article series you'll see details on the history of how these railroad spikes have been made and you'll note with interest that they've been made by machine and in enormous quantities since very early in the history of railroads

On 2022-09-04 by Matt

Do you know how the average dog spikes are manufactured? I recently saw this "double spike" at a blacksmithing event, really interested to know how it was made. Was it a defect?

@Penny,

You show a railroad spike, whose history and ages are given above on this page.

Your RR spike is quite rusted. But there might be a clue to its age if you notice the direction of splits in the iron and compare those with

On 2022-06-06 by InspectApedia-911 (mod) - Railroad spike from Shawnee Oklahoma train depot.

@Anonymous,

Thank you for the photos in the question. I've been looking at this for a while.

I think the fact that you see what looks like a black coating on the spike surfaces and more that the coating is in good condition suggests these are pretty-modern railroad spikes.

Please see your photos and more-detailed discussion about the numbers and letters stamped onto the heads of railroad spikes

@Tyler,

For guessing at the age of your railroad spike,

1. tell us the location where it was found and what's known about railroads that run or ran in that area

2. see RAILROAD SPIKE AGE CONTECTUAL CLUES

You will find additional advice on guessing age by using more details about fasteners at

I found this railroad spike at a railroad that I know dates back to at least 1861 per local history and maps. Is there a way to date this, I know the railroad was in operation up until the 1970s, so is there a way to determine if this is older or newer? Thanks

@InspectApedia-911,

Thank you for the detailed information about the railroad!

On 2022-06-02 by InspectApedia-911 (mod) - railroad spike from Norfolk and Western Cripple Creek Extension

@Billy Norman,

Thank you for the question and those great photos of an antique railroad spike. The size and shape of these spikes was fairly consistent and their fabrication was by machine so early in their history that this is a helpful example of dating artifacts in part by their context and surrounds.

A bit has been written about the history of the Norfolk and Western Cripple Creek Extension, as perhaps you already knew.

It dates from 1882, and is shown on the map excerpt below, courtesy of virginiaplaces.org - retrieved 2022/06/02, original source: http://www.virginiaplaces.org/rail/cripplecreek.html


And as you so exactly pointed-out, this railroad line was abandoned (under N&W ownership) in 1985, continuing today as the New River rail-trail.

If you haven't seen it, a nice history of the N&W railroad that includes discussion of the Cripple Creek Extension

is available (PDF copy) as

On 2022-06-02 by Billy Norman - spike found at P22 on the New River Trail in Virginia

I found this spike at the P22 markeron the New River Trail in Virginia (a couple of miles from Foster Falls). I assume this is from the Norfolk and Western Cripple Creek Extension before it was removed and the trail was constructed.

Are you able to roughly identify the age of the spike based on the shape and size?

Thank you,
Bill

Thank you for your help,
Billy Norman

That spike is so un-even, with larger tip, that it looks as if it might be hand forged. Are there hammer marks?

On 2022-04-02 by Inspectapedia Com Moderator - nail found in tire on Florida coast

@Mike w,

Thanks for a real challenge. I don't think it's a RR spike.

That eccentric or off-center head found on spikes is common on railroad spikes but the diameter of the spike looks to me rather small to argue that it was used on a railroad.

If you can see splits or separations running along the long-axis of the spike shank that would give some clue to fastener age as we explain

at NAIL AGE DETERMINATION KEY

On 2022-04-02 by Mike w

@Inspectapedia Com Moderator,

Found this in Central Florida on the space coast near the St. John’s River. Thinking an old railroad spike trying to determine how old it is. I am told there was an old confederate railroad that ran through the ranch. I was lucky enough to find it in my tire. This is the spike out of the tire.
