Hello all. I have a challenge for you. The first picture is the upper level of the N scale layout I would like to build, and the second is the lower level. Transition is via two helixes on either end of the benchwork. There are a number of features that I really like about this layout. First, you will notice that it is an interchange for lots of traffic. The east-west line is a UP mainline that runs from Salt Lake City via Boise ID and continues west to Portland and the Pacific coastal region. The north-south line is my own EPN&S, a subsidiary of the BNSF, running from Spokane WA and points north, south to Reno NV. The second feature is the recycling plant. Recyclable materials are brought in from both north and south, dropped off in the yard, where it will be sorted, moved to the plant by the local switcher where it will be processed into a large number of usable products, loaded, picked up and taken back to the yard where it is once again classified, set out, picked up and taken either east or west to customers by the UP. There are some local businesses that are serviced along with businesses both north and south. This is also an east-west Amtrak route so there is connecting passenger service to and from the north and south. As well, there is a "Gambler's Special" that runs from Spokane to Reno each Friday, returning Sunday night. With trains set up in the lower staging prior to operations and the configuration that allows continuous running it promises to be an interesting layout to work. The downside is that it is a complex layout to build. There are a lot of tracks and not a lot of scenicing, which I would like to have. The challenge is to come up with an N scale track plan with only a single level (multiple elevations are a plus) that will fit into the bench outline in figure three. Continuous running is a requirement plus some switching. Water features are also good along with some nice senicing opportunities. The era is the mid to late 80's or early 90's. Location is a small town to rural to wilderness Pacific northwest setting in either the foothills or mountains. I'd like to avoid mines and logging operations. I know that these are popular switching industries, but for me they are a little too popular. I would like some sort of switching industry or plant that is a bit unusual. The 32" sections on either end are to accommodate 15" radius turns. They can either be under a mountain or in the open. At A there will of course need to be a bridge or other connecting platform. I'll leave that option open. Those are about the only requirements that I have. Any plans, ideas, suggestions you have will be appreciated. I have attempted several different ideas, but an afraid that I have developed tunnel vision and am unable to come up with anything that diverges significantly from the original plan.
