Crossing Gates

[mikec069]

Good day all:

I have a grossing gate with two bars that come down as the train approaches to keep the autos from becoming scrap metal.  It works, but as the stock rolls past center the gates go up a bit.  This is because the 'sensors' are at each end and nothing in the middle.  Is there such a gate, PREBUILT, that will go down as the train approaches, stay down as the train passes then raise after the train has complete the crossing? Must be compatible with E-Z Track.

Thak you and happy railroading holidays!!
