Thanks for another interesting video Steve.
Looks like our Class 08 shunter (Link...

I think I can see that there's a ratty little driving 'cupboard' in the coach when it's being propelled. An arrangement like on our UK Class 153 single car DMUs (Link...

And it seems funny that they've got the loco going bonnet first when it's leading, you'd have thought it would be easier for visibility to have it running cab first. Though there may be a reason (there usually is).
Cheers, BW.
