I have recently converted a new Large Scale Thomas to battery R/C.
This thread at LSC shows how I did it:

What a great looking loco. Nicely made. Just runs way to fast at 12 volts.
Tony,
You always make it look so easy,
I bow to you Master

Thank you for the compliment.
It looks easy because it is easy.
The secret is to try and keep any wiring as neat as possible.
The only soldering necessary with the Thomas installation is the output of the ESC to the motor terminals. Even that could be avoided if if the installer removed the track pick ups and fed the old track pick up wires back up to the top of the chassis.
