Is it possible to add the power functions to Western Train Chase? I recently got the Red Cargo Train and it's a great Lego set but a Cars themed train going around my Christmas tree would be even better.

Has anyone gotten the power functions to work on the Western Train Chase set? Are the trains compatible with the normal Lego tracks? Is the "magnetic car connector" at the same height and compatible with the connector on the Red Cargo Train?
According to the product description on the LEGO® webn site, the LEGO® Power Functions Train Motor 88002, can be used to motorise the Western Train Chase.

The train wheels normally fit directly to this motor, so I'm sure that this train can be used on normal LEGO® tracks.

Looking at the instructions for both the Red Cargo Train and the Western Train Chase, I'd say that the magnetic couplings are the same height.
