Part of the later Doncaster-built EWS "Coalfish" ballast wagon conversions, these MHA 'Calfish' Ballast wagons were rebodied from MGR HAA hoppers between 2003–2004 under TOPS code MHA.  
Painted crimson with a visible running numbers and ‘EWS’ logos, this triple pack of EWS MHA Hopper wagons pair perfectly with the EWS Class 37 (TT3037TXS) to create a realistic freight pulling scene.
