Howdy @"Muddy Poppins"!
I'm just going to throw out my understandings of what you're asking about for each number you listed, so here I go!
1.) That would be right! @"Ucwepn" was able to mod one of the TrackMaster Revolution engines to have the TrackMaster/TOMY wheels, enhancing playability to some degree, but he and another member of the forum found this mod rather difficult to undertake, due to the tight fit of the wheels onto the geared axle and the half-axles to be removed without causing any damage to the plastic chassis.
2.) Any trains from the TAKARA TOMY Corporation are most definitely worth the expenditure and wait; the "Mystery of the Blue Mountain" pack that featured the Pre-Sodor Victor easily shows off the build quality for the mass-produced product, and the engines, track, cargo, figures, scenery, rolling stock, and accessories have a great deal of durability, so they can endure quite a bit of play for many years. To reiterate, four or five of my oldest engines are from the Plarail Corporation, and still run like new, despite being 11 years old.
3.)You can change the turbine(I think that's the proper terminology; @"Ucwepn" might know more) within the motor to enhance either speed or pulling power, or even both! Each Plarail engine is different, with some having 2-Speed motors (Default and faster), Hi-Power motors (faster, but stronger; takes a bit more to make the gears skip), and things of the nature.
Hope this helps!
