to a 110v? I have had some reference to purchasing a 220v transformer and then
buying a converter. If that is the way to go then what type of converter? Thanks
for any help.

I had good luck with a stepup transformer I bought at Radio Shack. You need to
get a real transformer in my view, not one of those things that can run
shavers... When you buy a 220V speed regulator, you will find some amperage or
wattage requirements molded or printed on the case... hew to those in doing your
stepup shopping. You can go larger but don't go too much smaller.

Alternatively for a non LEGO solution, go with any reliable supply of 12V DC of
sufficient amperage and splice it in to a power lead wire.

Alternatively/alternatively, you can cut a 9V wire and splice a 12V connector on
it...(1) the 12V trains will run on 9V, just not as fast. And if you operate 12V
bulbs on 9V, they will last longer. I am not sure about operating accessories
like remote switches though.

Hope that helps.

1 - I have done this, I got some 12V connectors (as service parts) from Conan
and used a jeweler's screwdriver to mount them on a stripped 9V wire that I cut
in half... one wire cut in half will give you 2 12V/9V power convertor leads.  I
will argue that it is almost not impure, but not quite. You're technically not
supposed to cut 9V wires, although apparently if they sold 12V connectors you
were supposed to at least be able to restrip 12V wires so I dunno.  Nice little
argument you can have with your self some rainy day, if you're so inclined!

(...) A 12V transformer supplies full wave rectified power (humps on an oscilloscope). Mine puts out up to 14.7 Volts no load to the track. The "DC" to the switches is also 14.7 Volts max. There is an AC output that gives 17 Volts AC no load. (...) (20 years ago, 20-Jan-04, to lugnet.trains)
