I recently pulled out all my HO sets from when I was younger, they've been boxed up for 25+ years.  Because of that, many of my engines and controllers didn't work.  Since i was doing this for my 2 year old, and to not disappoint him, we went to the local hobby store and picked up a Bachmann set; small track, controller, 1 engine.  Just enough to excite my youngin.

Anyway, i've been looking at the "Thomas and Friends" series of HO and I'm curious about the connectors on the engines and cars; they look different.  So my question is, if I purchase a Thomas engine, will he be able to pull my other cars, new or old? 

Thanks,
