And how do you intend to make them go forward and backwards?
Use something like an X10 system?


Some model trains do run on AC and are getting pretty high-tech
these days.

Yep, I remembered therewas some systems around. Shades of not having the
room to set up some track and build my own.

If I was to wire the AC adapter directly to the tracks, ignoring for the
moment any modifications required to accommodate, would this be asking for
trouble?

Well, they would need modification to accommodate the AC.
yes, a wonderful invention called a bridge rectifier.

I do hope the OP isn't serious.
Only a fool would modify their trains so they could run on AC tracks.

DCC is all the rage now.

Doesn't DCC work over AC? Albeit, not the same AC from a power pack, or
from mains.

I have already put one train under radio control, using the rails to
supply the radio gear and motors.

DCC is a pulse width encoded square wave.
Normal DC trains are modded to work with DCC. A bridge rectifier
converts the square wave into DC for the PWM motor control. A lot even
come with DCC encoders built in now. They are still DC motors of
course.
