Capital One Credit card Commercial

I bet all of us have seen the Capital One Commercail with the family that jumps into a boxcar on a train because their credit card miles are blacked out. Now here is the funny thing.... at the end of the Commercial when the Granny jumps from the car down the embankment, you see several older painted Coaches.... they are definately heavyweights.... they really look out of place... anyone know where it was filmed? And why they chose to add coaches on the back of a freight train.

That equipment appears to be from either Australia or New Zealand. The what we would term "baggage" car (parcels van?) is a giveaway.
