I have the same problem with my original Polar Express. If you remember John we went into a lot of detail on the issue. The problem was the lack of real estate in the body structure. Not only that the gearing probably would have a problem handling any more torque then what is needed for a few cars at best and forget about any grade you may throw at them. I think the Hogwarts engine would be even more problematic.
It was really short sighted of Lionel to build any engine with such limited capabilities, but to sell twice the add on cars then what they could handle is just simply silly and a little sad considering how disappointed it made their loyal customers.
What Lionel needs to do to redeem themselves in my eyes is to offer us an O-36 Polar Express engine with some guts built in, as well as a kick *** smoke unit. Their new control system Lion Chief Plus with electro-coupler and sound will cause me to open my wallet in a heart beat.
Then Lionel and I can be all Lovey dovey again.
