We're on vacation here in NZ (typing this from the Franz Josef Glacier)....took the TransAlpine train from Christchurch. I have taken a couple of pictures (arrived a bit late and only have a few seconds to snap some before they pulled out) and when we get back I will post them. The cars were refurbished in 2001, and look nice and are comfortable, though they are showing their true age on the outside. Perhaps someone will be able to identify the motive power when I post the pics. Kia ora!
