breaking up trains may also be needed.

Servicing Platforms
Tracks should have a minimum, uniform spacing of 20' between track centers. However, as you can see in several photos, some prototype yards alternated wide with narrow platforms and track spacings. Service p latforms should be placed between all tracks on which cars are to be serviced. The e dge of the platform should be approxi mately 5 ' 6 " f rom track center. Concrete was preferred for the platform surface, with the top of the platform level with the top of the rails. Facilities such as light posts, brake-shoe racks and service outlets located o n the platform should be off center in order to provide wider passageways on one side for service vehicles. Supply lines and service outlets provided the water, low- and high-pressure air, DC a nd AC electricity and steam needed for

servicing the cars. These facilities should be modeled. In large yards, the supply lines were placed underground in tunnels or conduits with outlet boxes placed to service each track. The location of each is described here briefly. Water C old water hydrants were placed at car length intervals on the platform for drinking water and cleaning purposes. Hot water was also supplied at less frequent intervals. Low-pressure air connections (for cleaning) should be spaced at the same intervals as the cold water hydrants, and located on the platform. Compressed Air High-pressure air connections (for brake charging and test ing) should be provided by either a double connection at the middle of each track or a single connection at each end of each track. These connections were located between the rails. Steam Steam connections (for heating

and cooling cars) should be provided in the same way as high-pressure air connections. Electrical Outlets Electrical outlets may be located either at the center of the platform (thereby serving two tracks and t herefore needing two receptacles), or at platform edge (serving one track with single receptacles), and spaced at car length intervals. Outlets for battery charging (usually 32V DC) and 220V AC for air conditioning are needed. Therefore, the number of receptacles needed at each location is doubled (one DC, one AC).

Pullman Company
In a multi-railroad terminal, the Pullmans were cleaned and linen exchanged at a Pullman Company facility serving all railroads, or at separate facilities for each railroad if traffic was voluminous. At its peak (about 1940) Pullman had ten laundries and used 23 commercial laundries, had 39 commis-

An open air shed covers repair tracks with pits for underbody and truck work at the Amtrak (ex-Pennsylvania) Chicago coach yard. There are a number of small details - ladders, wheel sets, bins - and the brick yard buildings which could make a railroady scene on your layout after kit bashing. This yard and structures have been rebuilt by Amtrak.
