Did the prototype ever carry passengers?
How long was it in service for?

I very much doubt it ever carried paying passengers, since only one carriage was ever built/converted. Looking at the pictures on the Southern Electric Group's website, there's a class 73 visible in the cab photo, so it's likely that the unit couldn't even move on its own (I suspect that the 424's control system, assuming one was even installed, wasn't compatible with the rest of the CIG, so it probably couldn't be driven from the new cab).
Thank you. I'm sad I never got to check it out - it was an interesting concept...Was indeed scrapped at that time.
