The body building firm of MCW had a long history of construction at both its Metropolitan Cammell premises at Birmingham and the Weymann sector at Addlestone in Surrey. It sold limited numbers of integrally built Olympic and Olympians saloons using Leyland running units although these were more popular overseas. With the new design Leyland National due to be released in 1970, the conventional build of MCW buses were under threat so the company entered into an agreement with Scania to build the integrally bodied Metro-Scania saloon and the Metropolitan.
In 1978 after this agreement had come to a close, MCW launched their own chassis the Metrobus. Although mainly seen carrying its own builders design of bodywork, the ladder-framed design of chassis was made available to other coach builders. The new vehicle quickly became established in the bus industry, with London and (on native ground), the West Midlands PTE becoming purchasers, along with most other PTE fleets.
The first 5 of such vehicles for the West Yorkshire PTE arrived in 1980 , and numbered 7501-7505 (JUM 501-5V) and were of the DR101 type which incorporated a Gardner 6LXB engine, hydraulic brakes and a 4.95m wheelbase.
Originally operating from Seacroft garage and later Torre Road (Leeds), they passed into Yorkshire Rider ownership on deregulation in 1986. WYPTE and Yorkshire Rider acquired a total of 105 metrobuses up to 1988 between them which included 10 with the less common Alexander body.
In August 1994 Merseyside PTEs successor Merseyside Transport took delivery of 7505, 7501 – 7504 of the first WYPTE batch, together with 7506, 7508, and 7510 of the PTEs second delivery batch. Here 7505 was entered into the fleet as 3505 and based at St Helens. Its stay was relatively brief and by September 1996 it passed to the Scottish operations of Earnside Coaches of Glenfarg near Perth.
It was offered to the Keighley Bus Museum in September 2002 by Earnside Coaches proprietor, David Rutherford and arrived at the museum still bearing that operators yellow livery whilst awaiting its turn for preservation. It attended the KBMT Metro 40 event at Bradford having had various remedial work and mot but as yet unpainted. Following a dedicated plan of work carried out by various members of the Keighley Bus Museum members which included welding, and paneling, new air bags and compressor tanks, the bus has since been restored and repainted into Metro Verona Green and Cream livery.
