Purist approach is to use a 9V train speed reg and LEGO(r) wires from the
speed reg to your motor(s), possibly through the polarity reverser switch to
give control. The speed reg is powered from a wall wart trafo so if you buy
a UK train set or UK used speed reg (should not be too hard to come by) or
even pay LD's high price for a new one, you should be all set. The UK wall
wart will have the appropriate 3 pins for your funky mains points and will
be 220v compatible.
The wall wart from a speed reg can also power an RCX that has the power
connector (1.0 but not 1.5. I do not know if they put it back for 2.0 or
not) if you want to go that way...
Hope that helps.
