You didn't mention how big your layout is or where you are planning to place your panel.
This is the control panel for my 5ft x 10ft HO layout. All layout power is routed through the switch
on the left. The next 2 switches are power for DCC and DC throttles, each having its output fused.
The next switch selects whether the track is connected to DCC or DC throttle. The next switch
determines whether a #1157 automotive bulb is connected in-line or bypassed to track power.
Additional switches are spares. Additional fuses for ancillary power supplies. There is plenty of
space for additional "stuff" on the front panel. The panel opens to the left, eliminating the need
to wire upside down if the panel is hinged to open down. It is mounted flush to and below the
fascia so as not to obstruct the aisle.
I also use the Power Cab and thought about getting a holster for it. However, I wanted the capability of
handheld and console operation. An angled holster mounted to the edge of the layout allows for both
modes of operation.
