More wires than I thought

The club layout is undergoing a huge renovation project. We're almost done with the main wiring phase. One of my tasks was to design the electrical system for signals and power distribution. Where the old section of layout had 1, maybe 2, power blocks, the new has six.

The main lines wound up having 3 sets of wires feeding the various points around the layout. The first 2 sets would be 1 were it not for the booster being located right in the middle of the block. The 3rd set is to run power from around the duck-under bridge, so there's no need to run power across (underneath) the bridge.

Because of splits like this, it turns out that my panel was completely underdesigned to handle all the connections that were required. The panel was designed to handle 6 sets of bus wires but will probably wind up supporting 14.

Fortunately, the mounting board was quite large and will be able to support the extra bus connections. There was even an autoreverser added for a reversing loop that I missed in my plans.

The installation of the panel in the middle of the bus rather than at the end created twice the connections as normally needed. Special wiring considerations added yet more connections, so the power distribution panel unintentionally became more complex and much fuller. A seemingly larger than necessary mounting board is handling the changes well.
