Thank you for your offer for assistance.
Attached are the schematic and control panel drawings for the model railroad switching system.
Each circuit works correctly.
You monetarily activate a switch on the control panel to the up position, the turnout changes to the diverse route and the bipolar LED (Red/Green) change state to Red.
You monetarily activate a switch on the control panel to the down position; the turnout reverts to normal route and the bipolar LED (Red/Green) change state to Green.
All thirteen circuits work the same and correctly.
The problem is other LED’s on the control panel will randomly change state when one of the switches on the control panel is activated up or down.
The turnouts are not affected and remain it the desired position.
I am utilizing a tower PC type power supply. This was changed to another power supply and the same problem persists.
I added .1mfd filter capacitors from the junction of R1 and R2 to +voltage and the problem persists.
The wiring from the control panel to the IC switching printed circuit board is less than three feet.
The wiring from the control panel to the “turnouts”, very up to six feet.
Any and all assistance would be helpful.
