Someone mentioned HST usage on freight trains?The prototype HST power cars had (have) a driving cab at the "blunt end" too. I seem to remember it was mooted they could be used on overnight parcels/newspaper trains.
I don't know if it's been photoshopped or real, if it's been shopped, they've done a good job. *edit: I definitely think it's shopped.
This is the rear cab on the Prototype, which I think was also incorperated on the production HSTs.
