I'll have five T-trak modules at Altoona this year - in Dave Ferrari's ad-hoc T-track group. West Hickory - triple - this was there last year - mostly sceniced Hickory Bridge - that's the new single track module that's a triple length and is pretty much done paired with Thompson - which for now is just a bypass track triple for the inner main around Hickory Bridge....unsceniced and two doubles on either end that swing the inner main around the back of Hickory Bridge module: Trunkeyville - semi-sceniced Jamison - operational but no scenery I'm using Peter Soborg's track weathering techniques that were described in MR. For the most part, I'm using Kato end connectors only, but Peco C55 inbetween. Full conventional roadbed and ballast construction. I've also painted and ballasted all the Kato track in the final versions. So if you're curious on what I've been tinkering with on 'single track' designs, stop and have a look, I'll usually be over at my vendor table.
