. Electric railway journal . linspection is a surprisingly small number of delays, asshown by the accompanying table of locomotive detentionsfor the year 1912. LIGHT REPAIRS Light repairs are made at the engine house in the Sunny-side yard. The building has two tracks devoted to workon electric locomotives, and these hold four completeengines, or eight units out of the sixty-six which areavailable for service. This track space has been found tobe more than enough for the requirements of the line, andit is seldom that more than two engines at a time are heldin the house. No work is done at the engine house which requires re-moval of the cab from the chassis or which requires raisingthe frames off the wheels. A drop pit is provided for wheelrepairs and for use in case a hot driving box necessitatesdropping one pair of drivers. This is, however, hardlyever used for this purpose on account of the freedom ofthe engines from trouble of this kind. A traveling elec-tric crane of 25 tons capacity is installed to serve the. Pennsylvania Locomotives—General View of Double Unit repair tracks, but this is also used for repairs to themultiple-unit motor cars, which are used on the elec-trified zone of the Pennsylvania Railroad and which receivelight repairs in the engine house. Pits between the railsare of course installed for the full length of both tracks. The live third-rails are not carried into the engine houseon account of the danger to the repair men. The electriclocomotives are, however, shifted in and out of the houseunder their own power by plugging a long insulated flex-ible cable into the bus line receptacles on the engines andthus connecting them to the live circuit. This cable isconnected through a heavy single-knife switch incased ina wooden box to the 600-volt feeders in the yard, and theother end is provided with a recessed plug so that no dangerexists for employees who make connections when the en-gines are being moved. Danger signs are always put uponexposed
