Grade Crossing gate question

[ns_gp60]

Alstom- Thankyou for telling me It's good to ge a reply. I don't what they mean when they " crossing toggle switch", thanks for clearing that up.

No problem! Anything I can do to help another railfan's knowledge out.

I knew as long as the train isen't on the island the gates will stay or go up also weight dosent matter. It is how well the wheels conduct electricity. Hy-Railers have insolated wheels so they won't set off the crossing. Since the track works on electiracal current sometimes when the roads have been salted down in the winter and the ice starts to melt it sets off the crossing and since it is in the middle of the island the gates wont rise!

I don't know about this. With the frequency of people running ordinary red lights going up, I wonder if it makes any difference at all. I prefer going to 4 crossing gates at all grade crossings, making it harder to drive around the gate.

I agree... That would give us signalmen work for a life time. It will never happen however. The reason is, if someone was to get passed the first set of gates as they were going down, they would be trapped by the gates on the other side..

Actually, under 49CFR222 FRA is allowing for full closure gate systems (4-quadrant gate system with gates located on both sides of the track in all traffic lanes) that may be used at crossings where the whistle/horn requirement is eliminated. These are in "quiet zone" locations with sensitive neighbors and/or horn ordinances. The approach side includes an electronic bell, a set of lights and gates, and the exit side is gates only. The exit gates are on a pivot and can be knocked out of the way by a vehicle attempting to exit the crossing. These have begun to show up in a several locations in our area, and to my knowledge there have been no major incidents or issues associated with the multiquadrant quiet zone installations.

I have seen simulations of a combination gate and a net system that rises from road to physicaly block traffic from entering crossing. And you thought $100,000. was expensive. [2c] as always ENJOY
