Which new track master set works best with the old track master trains?

I just got the Percy Sort & Switch Delivery Set for my first Trackmaster Revolution set (I plan on having it in tandem with my TOMY track and having newer engines run on the Revolution line to save filing them) and rather than using the Percy that came with it I decided to see if my TOMY Thomas would do it and he works with it fine so, by extension, the Trackmaster engines should work with it fine as well.
