I have a HUGE investment in 9V trains (think many thousands of USD) and was wondering how difficult it is to convert the newer RC/PF train systems over to 9V motors? Do the 9V motors fit? Does the base have space for the trucks? Is it even worth it (keep in mind, I hate batteries)? Converting the 12V trains to 9V was rather easy.
I haven't ventured out to purchase a set yet (even though they've been out for a few years now -- I'm lazy and cheap I guess) because they're all rather expensive (as we know), so I have not been able to check myself.
