Definition of TDAU :
Train Data Acquisition Unit (TDAU) is an electronic device installed in the Loco (Train Engine) to record all type communication : cab videos, train coordinates, time, events and instructions sent over any electronic systems on an the Loco.
Train Data Acquisition Unit (TDAU) is the pro-active and non-punitive use of digital or analog Train operational data from routine operations to improve train safety.
Objective of TDAU :
- Identify areas of operational risk and quantify safety margins
- Identify and quantify changing operational risks by highlighting when non-standard, unusual or unsafe circumstances occur.
- To use the information on the frequency of occurrence , combined with an estimation of severity, to assess the risk and to determine which may become unacceptable if discovered trend continuous.
- To put risk mitigation techniques
- Confirm the effectiveness of any remedial action by continued monitoring
- Compare Standard Operating Procedures with those actually achieved every day
Basic Parameters required for Analysis :
- Voice recording : Walkie Talkie, train driver to guard or train to control both ways, Magneto phone / Train intercom, Oral communication in the cab between loco pilot and the assistant
- Video recording of in cab and front view of the from loco
- Time and date
- GPS coordinates of location
- Train speed logs
- Break pressure logs
