Mountain, Cliffs and Waterfall

- Spiral Tunnel
- nearly 3 feet high
- concrete arch bridge

In the years that Chris Gray has been participating in NALUG's shows, he has wanted to have non-flat track. So, for this year's show he volunteered to fill the top of Kevin's transfer table with a small mountain layout. The result is a spiral tunnel track plan with two bridges. However, when John Koob thought about the result, he wanted to build cliff pieces to cover up the front exposed sides of the transfer table. And after that, Laszlo Szojka decided he needed a cliff going all the way from his floor-level ocean to the exposed top of the mountain.

This picture shows the "modules" from which the central/top part of the mountain is constructed. Colour was not maintained in the interior!

Here is the "male" plug of the system used to connect the 48x48 modules.

Construction Details

The basic mountain consists of 12 "modules" each built on an extra-large grey baseplate. All but 2 of these (the ones with the bridges over the stream) were designed to be able to have a mostly flat top, so that they can be stacked for transportation and storage. This then required 11 (one has 2) "lids" to go on top of the bases. Also, with this many large chunks, a method was needed to hold them firmly together. This was done with "T"-shaped connectors and sockets, as shown in the pictures immediately above. There are no BURPs (large rock pieces) in Chris's portion of the mountain - he loaned them all to John for the cliff pieces.
