Preservation Information
50454 was preserved in 1992 in a bulk buy of 12 Class 104 vehicles by private individuals Kevin Dowd and Robert Simpson. The fleet was eventually distributed over three heritage railways and 50454 was located on the Llangollen Railway on a long term loan arrangement with Llangollen Railcars.

After some restoration 50454 and partner 50528 were quickly put into service still in BR Blue livery. The set was later embellished with a "Blackpool" white stripe down the side.

During 1994 50454 underwent a heavy refurbishment and emerged in BR Green livery with half yellow panel.

In 1996 the roof was repainted.

The late 1990's and early 2000's saw the vehicle performing reliably, the set becoming a regular performer for many years, clocking up over 20,000 miles in traffic.

In 2007 50454 was fitted with a new cab after the original became so rotten that it was unable to be repaired. The replacement is, however, difficult to distinguish from the original and the route indicator blinds were refitted. The vehicle was briefly given a full yellow end to protect the new cab before the whole set was due for a repaint.

In the winter of 2008/2009 much of the skin of the bodywork was replaced and, after this rebuild, it was turned out in the 1964 livery of blue with a small yellow warning panel.

In 2012, the set became the first DMU since the 1960's to work west of Carrog on the Llangollen Railway's new Corwen extension, the set being used for driver training.

During 2013 the interior passenger areas received a mid life refurbishment, with the wooden panels being revarnished and the seating reupholstered.

50454 received a full repaint into BR Blue with a full yellow end during 2014, debuting at the Railcar Convention weekend in October.
