I've always thought Plarail to have better gearing, however. At least better than Trackmaster Revolution. I don't know about HiT Toys Trackmaster.
I remember how annoyed I used to be by that horrid grinding sound from my Tomy Emily's power tender. I once opened it up in an attempt to see what was causing it, but couldn't find any clue. It's safe to assume that all the flat types (including Tomy and HiT Toys [which was identical to Tomy]) are indeed louder than the other styles of drive units.
