Lionel Gateman Wiring

Use as many sections as you need to get the desired action, and if you use a variable accessory transformer tap you can fine tune the operation as well.

Track Power:

ACC power:

Agree with Rob. I use two insulated track sections for my Gateman and run it off the "B" tap on my ZW transformer. Smooth operation all the time. 

I just connected it to track power and a momentary on push button. I've done that with crossing gates and banjo signals too.  The grandkids like pushing buttons rather than waiting for a train to get there

Thanks to all.  Somewhere in my reading I think someone opined that it was Variable Voltage from Accessory Transformer was not as good as it kept the solenoid 'hot' and thereforel limited it's life.  Do you think there is anyting to that 

Again ....thanks so much

"Variable voltage" has nothing to do with whether the solenoid gets hot; constant voltage is what gets it hot. The coil needs to have some "off' time as well to prevent overheating. All variable voltage does is fine-tune the operation of the accessory.

Got it ..... sorry .... did not think it through 

To make mine "grandchild safe" I wired it on accessory voltage through a timer board which times out if the button is held. The kids have to press and let go before pressing again to make it work and prevent it from being on too long. Don't remember the board number but its one of those EBay Chinese ones.

Just to make sure as constant voltage could refer to a voltage that does not vary or an "always on" condition.

When there is no completed circuit (off) there is no power flow in the coil so it will cool.

I use a dedicated constant voltage power suppy (doorbell transformer).

  With it,  I use the Lionel under track pressure contactor (forget the #) AND a button to occupy any small fingers in need of entertainment. (could be phased (transf.) and used with isolated rail. I arrived at my combo by chance of convenience.).

  The news stand with spot circling the fire hydrant is choice #1 for most kids. If you want the gateman to get less attention, consider that one too.
