For years I didn't pay much attention to the whole Polar Express thing... I didn't care for the movie and I'm generally not interested in modeling passenger trains. Plus, a holiday-themed train layout wasn't something I'd typically pursue.
Fast forward to this year and getting a closer look at the Polar Freight starter set and accompanying rolling stock. The pleasant color coordination and more subtle holiday theme (i.e., not bright red and green) has won me over--so I'm definitely planning to build a Polar Freight train in the coming year. I'll probably begin with the starter set and over time add things like the tanker, the reindeer stock car, the hot cocoa car, the hopper, the PS-1 box, the wood box, the PS-4 flat/trailers, and the reefer.
So my question to the group is, what are your thoughts about power for this train? The loco in the starter kit is a bit unimpressive, so I'd definitely want to replace that. While I like the Polar Railroad GP7, it's not available in conventional, as far as I can tell.
Of the various Polar Express (conventional) steamers, is there one that's seen as being a particularly good choice? (model/year, etc...)
