Ramsey car-transfer apparatus

It was invented and patented in 1876 by Robert Henry Ramsey as a simple and rapid device for removing trucks at repairing shops, and for transferring car-bodies between rail roads of different gauges.

As the car passed over the opposite side of the pit, the new trucks were guided to fit on the center pins.

[1] The East Broad Top Railroad, a coal rail road in Pennsylvania used it in its Mount Union Yard up to the closure in 1956.

[3][4] In Ogden, Ramsey devices allowed interchange between the standard gauge Union Pacific and Central Pacific Railroad mainlines with narrow gauge routes on the Oregon Short Line and Denver & Rio Grande Western Railway.

Union Pacific operated extensive interstate traffic using the Ramsey transfer, such as shipping narrow gauge coal cars originating on the Denver, South Park & Pacific Railroad to Butte, Montana with Ramsey transfers when needed to account for the gauge breaks.
