Club member has the Lionel Jr Mikado with railsounds 5.0 cab number 9639. It derailed last night and had that "bad smell". Looked like he smoked the R2LC 13 board. I swapped it with a version 8 which I have a supply of those. The engine seems to run fine with all the 5.0 features.
The $64,000 question is... what is the difference in the 2 versions? And can you swap it like I did in a small Jr. Mikado?
I am hoping someone from Lionel chimes in here. They are the true experts on the details but I know some folks here would know as well.
Thanks,
Ted
