MEASURING ACCURACY OF MECHANICAL TYPE TRACK INSPECTION CAR

Mechanical type track inspection car YA210 has a measuring chord length 4.6m, its measuring accuracy being 19%. The accuracy has been improved to 12% by means of softer restoring springs. YA210 may be used up to the speed of 72km/h. There are prospects of constructing a mechanical type track inspection car with a measuring accuracy 10% and a measuring chord length 10 m. The new mechanical type track inspection car will have an integral type measuring equipment for superelevation of track, and a mechanical type automatic data processing equipment.
