Gunrunner John has it right.

Don't use any of the circuitry on those boards. Just cut the leads to the existing LEDs (thankfully the leads have some extra wire to work with) and power them with 12 volts DC and the 560 ohm resistor John suggested. The board even shows you which lead on the LED is negative. It looks like that board has seen better days anyway. Lots of ugly solder work there.

What a neat thing to have in your train room!
