DOT TEST TRAIN PROGRAM SYSTEM INSTRUMENTATION MANUAL - SIXTH EDITION

This manual describes track measuring instrumentation which has been developed during the report period and covers all instrumentation currently installed aboard the FRA test cars. The major emphasis of this report deals with the operation and calibration of the track geometry measurement system installed aboard test car T-3. Ancillary systems as well as equipment aboard test cars T-1, T-2, and T-4 are also summarized. New track measurement subsystems such as the alignometer, compensated accelerometer, grade, and magnetic gage systems are described briefly in this report. These systems are scheduled for prototype testing on the FRA test cars during the coming year, and will be fully documented in subsequent reports.
