I've also got one on order, and want to convert it to EM, so I've been in touch with Ultrascale and it looks, unfortunately, as if they won't be producing a conversion wheelset for this model, which is a shame, but they don't have a suitable wheel in their range and can't justify tooling up for one for the Class 14. Time to put the thinking caps on and work out a plan of action then!!!
