The Bison, a Br 85.

An older Marklin model of the Br 01.

Here's a Hag elok coming off the helix. This is one of many helixes on the layout.

Part of the helix with a smaller shattenbahnhof visible. In the main yard is a Dutch elok. Did you notice the train wreck
in the shattenbahnhof? It was caused by an errant locomotive.

A small yard with oil service facilities.
 

Here's an example of one of the many relay panels around the layout. These control train movement.

So many trains. So little time.
