Not illustrated. 1914 edition. Excerpt: ... lumber and care in building are used. 'President, American Flexible Bolt Co., Chicago, 111. Both authors have discussed the advisability of the standard car. I doubt very much if this idea will ever be consummated, even to the extent of the standard material idea advanced by Mr. Burnett. The difficulty in the way is the human element; if we all thought alike it would be possible. The Master Car Builders' Association has standardized the parts essential to interchange, and under this head may be listed couplers, air hose, wheels, axles, journal boxes and contained parts, brake shoes and brake gear parts. The Government has standardized safety appliances. This to the uninitiated would seem to settle most of the difficulties in car repairs, but we all know that very few of the Master Car Builders' standards are really standards in exact detail, and the Interstate Commerce Commission safety appliances necessarily give considerable range of dimensions and application within which their requirements may be fulfilled. It is difficult for one not in railroad service to appreciate the whole problem, and particularly the influence of interchange requirements. A railroad may be of low gradient, equipped with light power, and have a class of traffic that would ordinarily keep their cars on their own line, and the cars which would most economically fulfill all requirements for such a line and service can be readily imagined. In interchange, however, these cars might be required to go anywhere from coast to coast, in all kinds of tonnage trains, through hump yard trials and other tribulations never experienced on the parent road. Furthermore, a railroad car designer can never afford to worship standards in view of the rapid evolution in transportation. more
