Committee 2 - Track Measurement and Assessment Systems

Maintenance-of-Way Functional Group

Committee 2 is responsible for the development and publication of information and recommended practices regarding track measurement and assessment systems with an emphasis on current technologies; this includes systems capable of automated measurement and condition assessment of the track structure and its components such as rail, ties, fasteners, ballast, joints, and special trackwork.

The members of the committee had the chance to visit and tour UP's Heritage Fleet, located a few minutes away from headquarters in Council Bluffs, Iowa; the fleet consists of several restored railroad cars dating back to 1912, including crew, passenger and dining cars. Afterwards, the committee was briefed on UP's PTC mobile training facility; members visited the car and after they were shown the virtual classroom, they were able to test their skills in the training simulators.
Committee 2 would like to thank UP for hosting the meeting.

The Committee 2 2018 Spring meeting took place in Colorado Springs, Colorado on March 26 alongside the 23rd Annual AAR Research Review. After the meeting and following the track walk, members of the committee were able to ride BNSF’s geometry car 80 and NxGen’s car 391 on TTCI’s high tonnage loop. During the ride, committee members were able to experience firsthand the requirements and outcomes of both technologies.
Committee 2 would like to thank TTCI for hosting this meeting and BNSF and NxGen for making their research cars available.
