Yellow plant. The Track Relaying Machine (TRM) was built for British Railways and was previously owned by Track Engineering until purchased by CPRR in 2020. She spent most of her working life in and around Bristol before coming to Princes Risborough. She has already been in use lifting track for the Independent Line from Princes Risborough to Thame Junction and has been a major asset in completing the job!
Shortly after completing those duties, the TRM failed with some pretty serious faults and is currently out of service.
