Polar Express Custom Help

Hi guys, Planning a plarail/ trackmaster custom for the 'Polar Express'. Anyone know which model I should start with?

Depending on how close you want it to look, the current D51-200 is probably the best match.

Good idea. The coaches are good for the PE coaches as well. Removing the smoke deflectors and moving the light may be a challenge, as well as adding the front platform, bell, and cowcatcher.
