Another possibility I hinted at in a conversation with Bernie Kempinski was an On30 layout that was patterned after the Maine Two-Footers. This certainly isn't the first time I've flirted with 2-foot modeling in 1/4" scale. Back in my MR days, the very first plan Iain Rice and I collaborated on was an On2 layout (this was the days before On30 took off) based on Phillips (o maybe Strong), Maine on the Sandy River & Rangeley Lakes RR. It's never been published, but I did find the plan and have posted it here.
Bernie, always willing to be a trouble maker, and perhaps sensing a convert to O scale, quickly fired off a track plan for the layout area patterned after the Wiscasset, Waterville & Farmington. I'd forgotten about it until we were watching "Aerial America" on the Smithsonian Channel the other night. Basically, the series is an aerial tour of one state. the episode we saw was filmed in Maine and featured the a look at the Wiscasset waterfront.
Just for fun, and maybe to offer you some inspiration, I've included Bernie's trackplan here. The footpringt is very close to the current HO layout.
As I build my "simplified" layout - which still has several dozen turnouts and a lot of buildings I find a LOT that's appealing about the 15 or so turnouts on this layout.
But not this time - I have too much invested in the CV of the steam era to change at this point.
But I also think this will be the last CV layout - the next one (if indeed there is a next one) will likely be something very, very different.
So part of me wants to file this plan away on this blog so I can come back to it, just in case.
