Nice pics! I've done the tour twice I liked it so much. It's quite a cool thing to see when they fire up the engine by basically tossing a ball of fire into the firebox to get it going. The people doing that have nerves of steel as far as I am concerned, fire proof gloves or not!
Did the guides happen to mention what all the plastic was up in the engine house for? That wasn't like that either time I took the tour (I don't think). Maybe they were painting or renovating something?
