JACKS interlocking is now operational. Doesn't look like JACKS, just west of Mt. Union? Be reminded of a much earlier post, where I explained that JACKS is the interlocking immediately west of LEWIS. On the model railroad, this is the control point immediately west of LEWIS. As such, I call it JACKS. It is actually the entrance to Altoona staging.
Looking for some suggestions on engineering... I'm building my Granville Bridge on the workbench. It's a custom configuration of the Model Railroad Stoneworks Rockville Bridge kit. Amazingly, the specs are nearly identical (See The Granville Bridge Project).
Half of LEWIS interlocking is situated on top of the bridge deck. Specifically, three sets of crossovers. The bridge is made of Hydrocal. The roadbed is a half inch of Homabed. The issue is control of the turnouts.
