Ok here we go i was reading through the forums to find an answer to my issue but cant find exactly what Im looking for. When I crack the throttle on my 889b transformer some trains go like a bat out of hell when the train should travel like a turtle. Any suggestions on what I should do in order to make engines start off slow?

I always thought Tyco transformers started trains too quickly and they stop all at once instead of a smooth stop.... The ones I have again today live up to that same standard...

yes...get a better transformer! the smallTyco power packs were known for their sudden power surges, you can't really get one to operate a train slowly unless you put in a special circuit to limit power. The way they are wound are not conducive to realistic slow starts. So either get an MRC with pulse technology, or another with the momentum feature. some of it also has to do with 3-pole motors, they are not particularly well suited for slow speed start-up, either. Combine that with the Tyco pak, and you're going to be giving your scale passengers whiplash every time.

Old power packs control speed by balancing a motor against a rheostat. In cases where the two don't balance well, like a low-draw motor and a big old throttle from the open frame motor days, you can get jackrabbit starts. I've controlled that by wiring in an automobile tail light bulb in parallel with the track. Unfortunately, I don't think a little trainset power pack would produce the amperage to run the train and the light bulb both.
Double heading locomotives with similar speed and acceleration produces the same effect as the tail light bulb, but again, you need the capacity in the power pack.
