Hi all, Newbie to the forum and kinda sorta new to O gauge trains. As a kid I only had access to HO trains but recently was handed down my Uncle's collections of O Gauge trains which includes Lionel, MTH, K-Line, Atlas and William's lines plus some HO stuff. While I was boxing up some Marklin HO stuff he mentioned that it ran on AC which he preferred over DC - frankly it had never occurred to me before that there that some brands would use AC instead of DC. I purchased an MTH RailKing set around 20 years ago and having looked at the transformer (Z-750) saw where it was rated at 21VAC. The problem I'm having is being unable to run other lines on the the RailKing track. I've tested Williams and Lionel and found that both engines light up, though the Williams looks weak at full power and I'm coming to the conclusion that the Z-750 isn't delivering enough power for either of these brands to actually move their engines on the track.
I have a Lionel power supply but now wondering if I rig it up to the MTH track could it over power the MTH engine? I've searched around but it seems that most threads and site these days are all talking about RC which I plan on implementing once I finish my shelf layout plan but in the meantime would like to make sure I'm not running the risk of blowing up some of these engines that have been handed down and want to separate out any of the trains that don't run as I may be putting some pieces up for sale.
Thanks for any advice you can provide.
