Thanks Bill, 
 
Based on your reply, confirming how this BD20 is connected, you said 3 wires: “one logic, one common, one power”.  
 
Have you measured the “power” voltage @ the BD20 terminals 1 to 4 to confirm you actually have 5V? 
 
If you do, you should connect your “logic” wire to pin 3 to take advantage of the power provided.
 
Also, are you saying that with 5V power @ the BD20 terminals, the LED on the BD20 is NOT lighting with a train in the block?
