The Track Recording Car (TRC)

Originally known as the High Speed Track Recording Coach this Mk 2f coach was especially converted for the BRB Director of Civil Engineering and was originally operated under the R&DD's control and numbered RDB999550. 

Following major changes within the Research Division in the late 1980's it was transferred to the DM& EE and then to Railtest and renumbered ADB999550.

It is fully equipped with living accommodation, air-conditioning etc and was used extensively on all main lines to monitor track condition. It can measure various track parameters including rail top, cant gradient, twist, level and alignment at speeds up to 125 mile/h. 

The author was involved with the fitment of pioneering video surveillance equipment on TRC.

The present TRC is owned by Network Rail and was incorporated into the New Measurement Train until replaced by a Mk3 vehicle.

The coach is currently operating on its own again top and tailed with whatever motive power is available. The coach is operated by DB Schenker on behalf of Network Rail
