Train Cat - 1300807 - Structure, Railroad, Signal Bridge - Railroad Structures

Specific Item Information: Mainly used West of Pittsburgh, these signal bridges found Eastward in a few locations. The distinct rounded end girders were an iconic part of what is the Pennsylvania Railroad. Designed directly from PRR plans, this signal bridge has a larger distance between the bents for multiple track spacing that is greater than prototypical.

Road Name History: Railroad structures include but are not limited to stations, depots, yard offices, interlocking towers and tanks. A train station, railway station, railroad station, or depot is a railway facility where trains regularly stop to load or unload passengers or freight.

It generally consists of at least one track-side platform and a station building (depot) providing such ancillary services as ticket sales and waiting rooms. If a station is on a single-track line, it often has a passing loop to facilitate traffic movements. The smallest stations are most often referred to as "stops" or, in some parts of the world, as "halts" (flag stops). Stations may be at ground level, underground, or elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams or other rapid transit systems.
