I am new to this forum & model railroading.I have a lifelike ho scale w/powerloc track that I am trying to upgrade.I have a 18v AC 16v DC 7va max output power supply, and it does'nt move the train at all.I have maybe 30 to 40 pieces of track & 4 turnouts.I am looking for an inexpensive way to power this thing & right now all I can find is the MRC tech 4 200/260.But I don't even know if this is compatible with the terminal track I have that came with the set.I would appreciate if someone could give me a little advice on this subject or some links were I might be able to find something.I would also be happy to give you more info if needed.
