Scott Mann told me he did not believe the 3 rail scale market to be more than around 5% of the market.
If Lionel believes the same then us 3rail scale buffs are out of luck regarding Lionel.
For what Lionel charges, a scale correct valve gear, fixed pilot option with correct height over the rail, not a foot or two and included scale wheel option is the only way I would buy their product.
I'm with Aaron on the tinplate rail, but not everyone is going to go as far as I have converting Atlas 148 to 3 rail.
However, my hats off to Lionel for the quality of their TMCC operating system. I use it and it is dead nuts reliable.
I will go to RC control with battery power for all my locos and switch to 2 rails in the future. That is why I've converted half the layout to 148 with a n scale third rail and am converting the rest, the third rail will come up easily.
