Small trackside structures:
In my hometown the modest A&Y Ry had two 8x12 frame buildings with weatherboarding siding and gable roof. One was the "Oil House" and one the "Tool House"[the Tool House survived and today is used as an outbuilding in the former Section Foreman's son's back yard]. It was always located close by the Dual Motorcar Shed which housed the Motorcar and work trailer.
The two little 8x12 buildings housed engine lubricant/oils, grease for rolling stock friction surfaces, turnouts, etc, and stored hand tools-shovels, picks, spike hammers, spikes, tie plates, crowbars, etc.
Alongside the siding was a stock unloading ramp where a local horse and cow trader [and Veterinarian] received animals from the west. There was no holding pen at the ramp which made unloading and herding the four-legged types interesting.
Also the little 30x50 Depot had a two-hole outhouse, with entrance lattice screen covering the female side, located just across the tracks in a wooded area.
There were always rails and ties stored in track space between the 26 car siding and the main. The siding had small 16x30 "warehouses"; one for feed and seed and one for fertlizer, bagged concrete, mortar mix and the like. The warehouses were located between the siding and U.S. Hwy 220 with barely room between track and road to load/unload trucks.
A local General store leased both warehouses from the Railway.
The A&Y passenger service ended in June 1938 and December 31,1949 the Southern Ry bought and retired the A&Y bonds and folded it into the parent company.
A&Y #542 Consolidation is the only surviving piece of A&Y equipment. It is cosmetically restored[a former movie star] and stored at Spencer Shops.
