The Ebenezer Scrooge Puppet
This one's easy to miss, but Hanks also voices the Ebenezer Scrooge puppet, which the homeless man uses to scare Hero Boy into doubting that the Polar Express is real. "You are just like me, my friend: a scrooge!" the puppet says, frightening Hero Boy. "North Pole, Santa Claus, this train — it's all a bunch o' humbug!" Hero Boy does eventually notice that it's just the homeless man playing a trick on him, but we don't blame him for scurrying away anyway after hearing Hanks's booming voice reverberate through the moving train car.
