This vehicle was new in February 1958,built to Lot No 30294, and its first shed was Crewe South (5B) but it had moved on to Toton(18A) by 1959 and then went to Buxton (9D) by 1965. It was originally paired with DMBS M50476 and centre car M59184 when new but as related earlier was paired with its current partner, M50454, while at Buxton shed.

This car was obtained for preservation in 1993 but its restoration was somewhat prolonged due to its poor condition. It was, however, successfully dealt with and has since covered over 23,000 miles in preservation with its partner, M50454.
This coach was repanelled inside and new upholstery was fitted in 1998. In 2008 the first class saloon was completely refurbished with powder-coated seatframes, new upholstery and revarnished saloon walls. As with 50454 it entered service at Llangollen painted blue with full yellow ends, but later gained the "white stripe" livery for a short time. Following full refurbishment it was painted in BR lined green and retained this livery until 2009 when it was repainted in the 1964 version of the British Railways livery, blue with small yellow warning panels. For many years this set was used as "Daisy" at "Friends of Thomas" events but this honour has now been passed onto another member of the fleet due to the livery change.
