. Railway track and track work . ver the track daily instead of trackwalking. The car may befitted with an odometer for measuring distances. Some cars of this kindhave been equipped with sails and worked satisfactorily, but care is requiredin handling them. Hand cars fitted with seats are used for inspectionpurposes, and some of these cars are operated by small steam engines,while velocipedes operated by gasoline engines are now quite extensivelyused. Some of the most recent velocipedes have frames of bicycle tubing,with wire-spoke wheels, and have the bicycle style of saddle, handle barand driving gear. Some of these weigh only 75 to 100 lbs. Push Car and Rail Car.—The push car is a platform car not fitted withpropelling gear, and is used for carrying rails, ties, gravel, earth, supplies,tools, etc. The car in Fig. 189, with a platform 7 x 5y2 ft, and four , will weigh 450 to 500 lbs. The rail car or tracklaying car, Fig. 197,has no platform, but two side sills, to which the journal boxes are attached,. Fig. 189.—Push Car. and three or four cross timbers faced with iron. At each end are tworollers to facilitate unloading rails. A rail car 8x6 ft., with sills 4x8 ins.,wheels 16 to 20 ins. diameter, 2%-in. axles, and a carrying capacity of 10to 12 tons, will weigh about 1,000 to 1,350 lbs. A plank bottom may benailed to the underside of the middle cross sills to form a box for tools orsupplies. Flags.—The ordinary flag is not reliable as a signal when the staff isstuck in the ground; if the weatheris calm it hangs limp, while the windmay blow it parallel with the track or wrap it round the staff. This maybe remedied by having it attached to a staff at each end, or the staff maybe fastened horizontally to a post 4 ft. high, 8 ft. from the rail. In theTallman device the flag is wound on a roller in a cylindrical case, havinga slot for the flag. This case is hinged at one end to the staff and whennot in use folds against it (with the flag inside), whil
