hi, i'm working on track geometry system for 2 years. i'm reporting defects of track geometry, rail wear, eq.conicity and corrugation. and reporting graphics of course.

what is your measurement system's name? what country is it from?

i would like to chat about the work we do and the systems we use.

Hello, nice introductionary video to this topic. Please would advise where I can find out how the track measuring equipment works? Also where would I find out the acceptable tolerances to defects? Specifically, I am interested in track alignment, twist faults and gauging. Many thanks, regards D

Could you pls explain what is track quality index?
