I would like run wire from one of my accessory terminals to some lighted bumpers that are on a few "dead" rail sidings in my container yard. Can this be accomplished? If so, would someone mind explaining how to connect (solder) the red and black wires to it?
Thanks!
John

I don't have these but if the underside looks like this you looks pretty easy.
Clip the resistor lead off of the center rail and solder your accessory power to the end. Same for the common.
I add a diode in series with the resistor to protect against reverse voltage to the LED, makes them last a lot longer.
I am still a bit of a noob at wiring changes. Can you explain further?
A 1N4003 in series with the resistor. It has to be pointed in the correct direction to match the polarity of the LED. If the LED doesn't light with the diode installed, reverse the diode.
Thanks John!!
If you remove the center rail pin from the bumper track, you could simply solder or connect your new power source to the center rail connection under the bumper, where the solder connects the center rail to the resistor. You could make the connection with a plug for easy removal if needed.
