Control Panel

Here is the Control Panel with block and turnout controls in the center section, and room for transformers and accessory controls on the side sections.  I put it together with some old pine boards, masonite, a table saw and patience.








Even though I plan to use DCS and TMCC command control, I have concluded that it does not necessarily replace block wiring if you want to run conventional locos as well.   There are times when you want to be able to shut off power to a block.  So I am wiring to allow for command and conventional.  So much for keeping it simple.

Since I need block controls, I decided to splurge on the control panel.  I am wiring up the panel with 2 LEDs in each block (one red and one yellow) that indicate which “cab” (if any) is powering that block.  Also the controllers) for the z2500 switch machines (mounted on the panel also) have red and green LEDs which indicate which way they are thrown.





I did the track diagram with Microsoft Paint, printed it on photo paper, and sandwiched it between a masonite base and a 1/16" plexiglass cover.  The most tedious part was drilling holes in the masonite for the toggles switches, buttons, and LEDs, and cutting out rectangles to insert the Z-Stuff 2502 switch controllers.  The 2502s will be mostly hidden:  only their buttons and LEDs show.  The plexiglass only needed holes for the toggle and pushbutton switches.  On the paper diagram, I cut out circles for all the LEDs and switches with 3mm, 6mm, and 8mm disposable punch biopsies (think cookie cutters).

So the soldering begins. One half of the DPDT toggles select CAB A or CAB B for its block, and the other half lights up the corresponding red or yellow LED.  The LEDs will be powered from a 4.5V DC power adaptor through current limiting resistors.






This panel will be so cool that you won’t even need to look at the trains . . .
