This EWS HFA Hopper triple-pack brings realistic bulk freight operations to your TT:120 layout. Finished in authentic EWS livery on the chassis, each wagon features fine detailing and unique running numbers (354248, 354249, and 354250).
History
With increasing demand for electricity in the 1960s, several new generation power stations were built, which required a continuous supply of coal at a rapid rate. A new design of wagon was developed that could be loaded and then emptied via underfloor doors while on the move, in what were termed ‘Merry-go-Round’ (MGR) trains. 
Following the construction of two prototypes at Darlington Works in 1964/5, a staggering 10,702 hopper wagons were built at Shildon Works, with a further 160 turned out at Ashford. Another 460 of the ‘HDA’ variant were built at Shildon, these being basically the same, but had improved braking to allow them to run at 60mph rather than 45mph. 
All versions of the ‘HAA’ carried 33 tonnes of pulverised coal. Other variants of the HAA included HBA, HCA, HFA, HMA and HNA, all of which had subtle differences but were essentially similar. The last MGR trains ran to Longannet power station in Scotland during 2008, and after that, only a small number of a CDA variant, converted for use on China clay traffic, remained in use.
These wagons were supplied with an aerodynamic canopy and could operate at 45mph when loaded. The wagons in the triple-pack each have different running numbers.
