Thanks!
Yes,if as I said the push button is spdt or has 3 leads. A toggle would work better because you would not have to hold it down. Here is a diagram for relay contacts. The switch or push button would have to have 3 connections just like the right side of the relay.The switch has to make/break the circuit.
The red wire would go to a 12-14 volt transformer hot tap.
The black wire would go to the transformer common (U on a ZW) and to the common of the switch.
The white and yellow wires would go to the other 2 switch contacts. If the gate works backwards simply reverse the wires.

Any SPDT toggle at Radio Shack would work. Follow the wiring instructions and it should work.
Now if you want it to work with the train,I would use a relay. This can be done if you can make an outside insulated rail. I can make you up a setup that should work if you are interested. I need to know what transformer you are using and could send a diagram.
Since you asked for a push button here is one of many with 3 connections SPDT. RS does not seem to list one.

Here is one a bit heavier,a better choice
