Railroad Lamps

Railroad lamps are distinguished from lanterns by both function and design. Lamps were generally intended to be stationary, were generally made of a sheet metal or cast metal body, and used lenses to amplify light from an interior light source. Lanterns were designed to be portable and used globes which were surrounded by a metal frame. A wide variety of different lamps were used by the railroads, including semaphore lamps, classification lamps, train order lamps, bridge lamps, marker lamps, and switch lamps. This page provides a brief look at some of major lamp types used by railroads. Note that you can also find pictures of lamps in our historical catalog pages -- see Library -- and a brochure on lamp maintenance.

Above Left. An Adams & Westlake Model #270 marker lamp marked "G.N. Ry." for the Great Northern Railway. This type of lamp was usually used on the caboose at the rear of the train. Above Center. An Adams & Westlake Model #169 switch lamp with a bellbottom base and marked for the Union Pacific Railroad. Note the two narrow cylinders coming up from the base, which indicates that this lamp was attached to the switch stand by a "fork mounting". Above Right. A train order lamp made by Adams & Westlake and marked O.E. Ry. for the Oregon Electric, an interurban operation. The train order lamp had two lenses on opposite sides of the lamp body.
Above Left. An Adams & Westlake semaphore lamp. Although this particular example represents a common style of semaphore lamp used by North American railroads, it was actually used in Argentina, having been manufactured under patent arrangements by a British company. Generally semaphore lamps had one lense. Photo courtesy of Luis Paupy. Above Center. A classification lamp marked for the New York Central Railroad. This may have been used either on a locomotive or tender.Photo courtesy of Mike and Julia. Above Right. A lamp which resembles a small semaphore lamp with a single amber lens and marked for the Union Pacific. The small size of this lamp and the amber lens suggests that it was a slow-order lamp used to indicate work at trackside. Update: A former Canadian Pacific employee emailed us with the following: " I suggest it is probably a Yard Limit sign lamp as ones almost identical to the one pictured were used on the CPR for that purpose.  When I was a boy the CPR finally installed block signals on the transcontinental mainline through my home town of Salmon Arm, B.C. and after that the Board of Transport allowed them to remove the oil lamps from the Yard Limit signs but there use continued where there was no block signal system e.g. branch lines, secondary mailines.  The Yard Limit sign was a yellow. diamond-shaped sign with "yard limit'" in large letters and a circular hole behind which the single lens yellow lamp was mounted and through which the light shone.  It stood on a metal post about head high. Of course the specific style varied from railway to railway." [Thanks to Doug Turner]

Some railroads painted marker lamps safety yellow rather than the traditional black color. Above Center.  A crossing gate lamp manufactured by Dressel. Photo courtesy of Bill Tarbox.
