It appears some modellers' wishes have been catered for by another manufacturer.
Despite all of the 'talk', the only big difference is the addition of lighting and augmented DCC functionality, and that uncoupling device ... at what price? The 08/09.
Still waiting for the A/S 40, Black 5, 8F, Parallel Scot, Jubilee ... perhaps a hydraulic Warship 42 ...
