Was able to run the Milwaukee Road Flyer Chief Northern last Saturday at the North Penn S Gaugers event. As a matter of fact, I didn't run it that much as other club members, who loved the engine and its' performance.
After all the complaints I have heard about manufacturers, I thought some good words were in order.
Also there were 2 Polar Express Berkshires there as well. Both performed excellently and were crowd and user pleasers. Flyer Chief is great because it runs on DCC (as well as AC, and DC).
