N-Scale Tube Tunnel V2 by jeff_j3ffr3y

Last crawled date: 3 years, 4 months ago

Using design cues from the Hudson River tunnel this tunnel comes in sections. There are enclosed and exposed 100mm sections along with grade changing couplers
V2 - I thinned the walls on pieces because it was unnecessarily wasteful. The main sections are now 100mm long. The window/access sections have a low facing wall to prevent any derailments from falling out and over the 5000' cliff. I made two sets of couplers to change the grade, either 2° or 4°. That's 2.2% and 4.4%. There are sections to grade up or down. A portal end connector assumes a grade entering the tunnel at 4° to mate with a vertical portal cap.
