I had a look at DCC mods for Lego train motors, but people seem to have used
N-gauge DCC decoders so that they can fit the decoder inside the motor casing.
This may be good from a space saving point of view, but I'm not sure about the
power ratings of the decoders.
Lego trains are up to four times the size of N-gauge in each direction, that's
up to 64 times the weight, requiring 64 times the power to move them. An
N-gauge DCC unit won't be rated to 64 times a typical N-gauge load, so surely
Lego trains are overloading an N-gauge DCC module?
Since DCC conversion requires disconnection inside the casing, between the
wheels and motor anyway, why not use an O-gauge DCC module inside the loco body,
bringing out the wheel contact connections on a wire? There's usually lots of
space inside the body for a bigger module.
This is the same principle as using two motors on an engine if you intend to run
long heavy trains, and particularly applies if you're crawling with a long
train.
