l be placed over the first pit at the eastend of the erecting shop. The center line of this pit is 13 feetfrom the wall and the other pits are spaced 22 feet from centerto center. This leaves a space of 9 feet between the center lineof the last pit and the fire wall separating the erecting andboiler shops. The purpose is to bring an engine upon the pit equippedwith the electric jack,unwheel the engine,place it upon trucks,and then move it out to the transfer table and thence to someother pit where the necessary repairs can be made. It has been stated that eleven pits are required in theerecting shop. Since the electric jack is to occupy one of thesepits continually,there are really only ten working pits, how-ever since the unwheeling and rewheeling of engines will there-by be concentrated at one pit,these ten pits will be sufficientto take care of the engines undergoing repair. Material racks for the storage of dismantled parts andwork benches will be placed between each erecting pit.

2. Selection of Machine Shop Equipment- The art of rail-way shop design has not yet been developed to the point whereone can turn to accessed formulae for the selection of theequipment for the machine shop. The best that can be done is tofollow what is thought to be good practice;but even then thesolution is not easy,for the ratios deduced from the comparisonof a number of shops are found to vary widely,and the figuresthus obtained have to be modified by personal judgement. It was at first thought possible to determine the equip-ment required for the machine shop by a graphical method,that is,by a series of curves showing the relation between the numberof erecting pits and each class of machines in existing shops.But after obtaining many such relations it was found impossibleto draw a curve that would in any way assist in determining theselection of the equipment. As shown in Pig.6 page 42,the scat-tered points indicate the number of four different kinds ofmachines in several shops of
