Control panels for DC block control.

My layout is DC block control. The way I set the system up required 3 panels. At Crescent City and Grants Pass, the 2 ends of the layout needed a plug in for each cab and a DPDT switch to select either branch line or main line power. The main control panel is located near the port which is the center of the layout. It has a plug in for each of the 2 cabs (I may also tie in a stationary Tech I I throttle) and 4 rotary switches to select which cab powers which section of the layout, which are the mainline, the branchline, the port and the logging spur. A DPDT switch controls the power to 1 leg of the wye. It selects power from either the Port or the branchline which requires the engine to stop on that leg of the wye as the switch is thrown, reversing the polarity to the engine. The plug ins are spaced so that the hand held cabs can reach all areas of the layout easily. The 3 panels are pictured below. The top 1 is the main control panel,  the next 1 is at Grants Pass and the last is at Crescent City.
