This DVD features the working of the RETB (Radio Electronic Tokenless Block) signalling system. Commissioned in February 1986 at Saxmundham signal box and replaced by a modern SSI (Solid State Interlocking) and axle counter system in October 2012. See the RETB and the replacement SSI system at work in Saxmundham signal box. The DVD also features footage from the cab of 57306 (with 57310 on the tail) as they make the last run of the RHTT (Rail Head Treatment Train) under the RETB signalling system, the weather was very dull and wet, but still worth a watch.
