Hi crew, At one time I had a diagram for running operating accessories such as the gate house using a relay to prevent power loss while the train is running. I have lost it and now I am rewiring and can't remember how to do it.
What transformer are you using? Does it have auxiliary terminals on it to run accessories?

Just to comment, there is no relay shown above, and none needed, either. A relay would be needed if you wanted to use a semaphore AND interrupt current to a block of track so one train would cause another to halt in apparent obedience to the signal.
In that case install a normally closed relay. It would have a pole of the relay magnet connected to terminal A in the diagram immediately above and also to one pole of the contacts which comprise the “switch” on the relay.
The other pole of the relay connects to the insulated rail in the above illustration. And the other contact on the switch would go to the block to be turned off . When the loco and trailing cars cross the section of track with the insulated rail, the circuit would be completed to the semaphore solenoid and the blade would pull down to the stop position. At the same time, the circuit to the relay magnet would be completed. That pulls down the plate of the relay holding a switch contact, and opens the circuit to the track, stopping the train.
Wish I could draw!
Yes, I am using a zw, a kw and an lw.
Hi Rob. I must have an older 145. I have only 2 connection points on the base of the unit. when I pulled the top there is nothing inside. I pulled the base plate but I am not sure how I would rewire to make this set up work.
mgbbob Hi Rob. I must have an older 145...

Is it possible you have a 45 Gateman?
Yes, you are correct. I tried running a seperate power wire from the C controller on my ZW and it seems to fix the slow down problem. I am not sure one a ZW if there is any fix voltage ports. I will need to do some reading. I powered my other "45" using an over the counter (ebay) 12 DC motion detector. Works great, in fact too good. There are some more focus motion detectors or I am try to shield the detection area. The DC makes for a very smooth operation.
I think that is what I did with the ZW. I ran a seperate power feed to the accessory and then used the insulated track to complete the circuit back to the ZW. I don't see any accessory power on the ZW so I may move this like over to my KW. For now I just added an additional power feed close to the Gateman and that helps alot. Thnks, Bob
mgbbob...I don't see any accessory power on the ZW
B & C posts are typically used for accessory taps when A & D are used for trains. The adjustable voltages are much more versatile than the rather limited 6 or 20 volt accessory taps on the KW when used with track activated equipment like the gateman.
