About Testing Department:
Testing Directorate plays a key role in design validation for all newly designed and / or modified rolling stocks through regular field trials like Oscillation trials, Coupler force and Controllability trials, Confirmatory Oscillograph Car Runs, Squeeze test, Emergency Braking Distance trial, Track Monitoring of Rajdhani Routes and also carries out some specialized nature of field trials like Rating & Performance trials, Jerk trials, Haulage Capacity trial etc. The Directorate also undertakes tests on all types of rolling stock sub-assemblies and their various components in its three laboratories namely Air Brake Lab (ABL), Brake Dynamometer Lab (BDL) and Fatigue Testing Lab (FTL). The ABL & FTL labs are accredited by National Accreditation Board for Testing and Calibration Laboratories (NABL) for testing compliant to ISO/IEC 17025.
