I bought a non scale coach out of the box used from my LHS and when the bell or whistle button is pushed (can't remember which) it plays the "All Aboard....This is the Polar Express" announcement from the movie. Wish there was a way to have it be optional.
Wow what a surprise! A hobbyist wanting more! HA! Thanks for sharing this cool video of a sure to be sorry i didn't have the $$$ to get one locomotive!
