Hi folks - I'm new to the forum. My sons love Thomas the Tank and I've picked up several of the new Bachman engines (Thomas/Percy/James) as a way to transition them from the wooden toys to the world of model railroading. I got only the engines - not the 'starter set' packages. I'm trying to run these on my dad's old HO layout that he pieced together many years ago. The transformers I have are old Tyco gold boxes - probably about 20-25 yrs old (some of this layout was actually mine when I was a teenager). They still work because all of our old engines run fine with them. However, when I put the new Bachman engines on the layout, even when I just barely turn the transformer on, they take off like a bat out of he** and run off the track because they can't take the corners that fast. Have things changed in the specs of how HO works these days compared with older sets, or is something else amiss here? Do I need a new/different type of transformer for these engines to get them to slow down? Any suggestions/recommendations? Also - these Bachman engines and cars seem to have trouble staying on the tracks of this old layout (my old trains do fine). I'm not sure if this is related to the engines running too fast or if it is a separate problem. Thanks for any advice!
