I'm a big Polar guy, even bought the Tri-Polar (Polar Bi-Polar) to run the PE freight, BUT they lost me on the Acela. That's OK though I think folks will buy it. They just need to keep some more freight cars coming. I think the Scale coaches though have reached their limit.
I would like to see more coaches (for selfish reasons). I like crazy long trains. I do agree 110% that they do need to keep pumping out freight cars.
