Howdy KumaChan!
To be quite honest, some engines have different gearing based on the type of motor that the locomotive possesses; for example, take the J.N.R. HD300. It has the bulky, black motor like a Plarail Thomas, Percy, Toby, Rosie, or Harvey, so it could be expected to be very noisy and somewhat fast or slow. On the contrary, as Ucwepn and I can both confirm, the HD300's engine is silent and makes the engine somewhat slow; what it lacks in speed it makes up for in brute strength.
Another example is the flat type drive unit that some engines possess; as James now has it in his redesign, his competition is the J.N.R. C57-1. Both motors are somewhat noisy(My C57-1 can be either quiet or noisy on any given day; can't confirm or deny redesigned James) and vary on speed and strength.
The same is said of the bulky C-Cell battery motors; quiet or noisy, fast or slow.
The only engines whose speed is really confirmed are 2-speed motors, or Hi-Power motors, both which practically guarantee high speeds, and great pulling power for the latter.
I hope this helps, partner; don't hesitate to ask any more questions if you need some help!
