OT7,
A bit off topic, but a plea for help cannot go unanswered.
I have no experience with FasTrack and probably will never get any. I would say that the common problem with the new Flyonel heavyweight cars and track work is the gauging of the wheels, that is, the backspacing of the wheel sets. But regauging the wheels is extremely difficult due to their construction. Lionel chose to make an eight wheel power pick up on these cars. Good idea, since it helps eliminate light flicker. But that means each axle has a plastic insulator between the short stub axles with the wheels on the end. Widening the axles can be done, but GREAT care must be taken because the axle stub has a spline that is extremely short. If you widen only one of the stubs, you can pull the stub out of the plastic center.
I can only look at the illustration of it in the 2015 catalog to suggest the construction of the cross-overs. I suspect that one or the other wheel in a set is "picking the point" of one of the guard rails on the crossing. You can verify this by taking a close look at the wheels as you pass it through the cross-over slowly by hand. Measure the back spacing on the wheels. Traditionally, that is in Gilbert Flyer, a US dime is a good way to check the spacing. On the new heavyweights, a dime barely fits. It should have a few thousandths of an inch more space. Now check the outside dimension of the pair of guard rails on the crossing. It should more than a bit larger than the spacing of the wheels. If it's close and upon inspection, and you notice a wheel picking one of these guard rails, you can also file both (I am guessing) plastic guard rails on the outside corner to guide the wheel to the outside of the guard rail. Make sure that you file the corners to a gradual taper to gently guide the wheel to the outside.
If the outside spacing of the guard rails is too narrow for the wheels to pass through in any case, your only solution is to widen the wheel gauging.
Of course, that is a work-around. Lionel should take better care in the gauging of the wheels, or at least design a cross over that can accommodate their own products!
Sorry for the long winded message, but I hope it's clear and it helps. Let us know.
