I am looking for some opinions and possible options for upgrading a Lionel C-420 from conventional to TMCC. And, whether or not to actually do it. I also own the TMCC equipped twin and think the two of them MU'd together would be neat.
Lionel's website indicates that all of the parts are currently available (electro-couplers, R2LC radio receiver (C07), RS4.0 generic C-420 & railsounds power supply). Or would it be better to look at ERR components?
Your views and/or experience would be appreciated.
