The Lego Car Blog Elves are confused today. They thought the Polar Express was a Christmassy cartoon film about a steam train, which – being Elves – they like very much. However Karwik, a TLCB favourite (and with builds like this one you can see why) uses the same name to wonderful effect on the side of this superb Volvo F89 articulated truck. You can see more of this, and his other creations, here.
