Very much welcome the development of this class of loco, although the first 'skinheads' appear to be missing at the moment. The auto uncoupling is the the outstanding item in this model, hopefully it will be spread across future releases, when the appropriate pcbs and dcc s/w are brought into use. Auto uncoupling in Blue Pullmans and EMU/DMUs would be most welcoming, not to mention coach rakes, for instance Pullmans. I note that SYE are missing, is this on account of AS releases, I wonder?
Where the auto uncoupler is concerned, the loco may well uncouple, but what of the attached coach/wagon, that will need the 'hand of god'. Accidental uncoupling can happen when there is only one coupling actively engaged.
