Originally conceived as a cheaper, more
reliable alternative to the Advanced Passenger Train in the early 1970s,
the British Railways Board authorised the development of a prototype
High Speed Diesel Train with two locomotives designated as Class 41.
These aerodynamic power cars were constructed by British Railways
Engineering Ltd at their Crewe Works and emerged in June and August
1972, fitted with Paxman Valenta 12RP200L engines, developing 2,250 hp.
When originally built at BREL’s Crewe Works,
the InterCity 125 units were considered to be diesel multiple units and
allocated as Class 253 to the Western Region and Class 254 for the
Eastern Region. With the introduction of Trailer Guard Second (TGS)
carriages, later power cars had no guard’s equipment installed and by
1987 most power cars were simply classified as Driving Motor (DM),
although they still had luggage van space, retaining a window by the
luggage door on each side.
Following problems with the power cars and
the operational ease of removing power cars to perform scheduled
maintenance, unit formations were abandoned, resulting in the Class 43
locomotive prefix being adopted. The fleet of 197 Class 43 power cars
produced between 1976 and 1982 were numbered 43002 to 43198 and are
officially the fastest diesel units in the world. The units have an
absolute maximum speed of 148mph (238kph), which is the current world
diesel traction record, set on November 1, 1987.
43078 was built at Crewe, along with 43079
and the locomotives entered traffic on February 17, 1978. 43078 carried
the name Golowan Festival Penzance between June 22, 1996 and November
30, 2003, having previously been named as Shildon, County Durham and
subsequently as Rio Crusader. 43079 carried no name during the same
period as 43078 Golowan Festival Penzance, but was subsequently named
Rio Crusader. The two locomotives are currently unnamed.
