Hello, today I've got a bit of a dilemma: I currently have a triple track layout and am wanting to build a tunnel leading out from a station on a curved 2% incline. Sounds somewhat simple but I have several concerns: 1. I cannot find any triple track tunnel mouths, nor do I know where to source general dimensions for them 2. With the 2% Incline, I am unsure to if it would work as the only foam inclines I've seen only allow 1 or 2 tracks, not 3, and since it's on a curve the outside, the distance covered by the outside curve is greater than that of the inside curve due to a larger turning radius, and since the total vertical height is the same by the end point the gradient is therefore theoretically less than on the inside line, and since I want the maximum gradient to be 2%, It would have to be the inside line which uses a 2% gradient. So what would I use for the other gradients? 3. How would I find a way to do the tunnel reliably inside a gradient? In case you may require information about the situations surrounding my railway, it uses 2nd, 3rd and 4th Radius for the curves on the layout, the 2% gradient starts just on a curve, which turns 90 Degrees before going into a single R600 track segment before curving another 90 Degrees again, before going of again. The Tunnel mouth starts about 1/3rd way on the R600 straight and ends with the curve, where the gradient ends. Any help on this is greatly appreichated. Best thanks, Travis
