Been as it's LGBT month:
I do have to admit, the 769's are kind of trans icons, starting their lives as electric and transitioning to diesel.
One of the few Pan-locomotives out there, compatible with power from not two, but three sources!
(I am supportive and also member of the community, just doing this in good humour lol)
How would you actually do that though?
Do you propose to replace the whole drive train during the conversion? or do you plan to have an electric drivetrain from the start? if you are planning on an electric drivetrain from the start it seems to me that you may as well also have the pantograph and transformer from the start and make it a bi-mode.
My consideration is to fit the body shell with an area to mount a pantograph.
But it may be sensible for GBR to have trains that can be converted to one or the other, having a cheaper upfront cost and actually putting pressure on the government to electrify routes.
