Interurban traffic, which commenced seven or eight yearsago, enlarged the scope of electric car building, introducing anumber of features and methods of steam car class of building, however, was developed from formertypes of electric cars rather than adaptations from steam carpractice. There has been and still continues a tendency to con-struct the bottom framing of interurban cars for a greaterhorizontal strength than conditions require, adding an un- necessary amount of weight, and not infrequently there hasbeen insufficient provision for vertical strain. This has beenshown by the early need of repairs, and in some cases the bot-tom framing has required additional bracing and trussing. Theupper framing of the larger straight-sided cars is braced and. A GRIP CAR FOR CABLE SERVICE trussed in the same manner as in steam car practice. Platesare usually placed on the inside of the sills, and latterly, onaccount of the long and heavy cars being built, a large amountof reinforcing of the other members of the bottom framing byplates and angle irons has been introduced. Many companieshave learned to their sorrow, and others are failing to profit bytheir experience, that the cost of operating extremely largeand heavy cars is more than the business warrants, or that theservice is limited by using a few large cars when the same out-lay for smaller cars would provide for a more frequent sched-ule. There are many disastrous results of small roads emulat-ing the example of the few extensive systems whose conditionsrequire large cars. For cable traction, grip cars with trailers were chiefly grip cars were usually open and the operating mechanism
