Sorry, double-post, but, this is an excellent site for railroad related images:
http://www.railpictures.net/And if you're going to include a yard, then read the 10 Commandments of Yard Design:
http://www.housatonicrr.com/yard_des.htmlDefinition: A "station" is a very loose term; "passenger stations" deal with permitting customers to board/de-board railroad coaches while a "freight station" is one that strictly handles the loading/unloading of freight. Typically freight houses were separate from passenger stations, but combination stations were utilized on low-traffic lines.
The structure in the image that Draco posted is more along the lines of an engine shed. Engine servicing facilities were seperate from passenger operations, off on a spur or at the end of the line. Usually adjacent to the rail yard. There are other buildings associated with it, such as fabrication buildings to produce parts (I'd imagine that InGen wouldn't want to wait around for a part to arrive from the mainland).
Different locomotives fulfilled different operational roles. Smaller engines were restricted to yard work and not for hauling freight along the mainline.
I have books and blueprints. Typically, at least for the Pennsylvania Railroad these structures were built from bricks.
