on the waldwick/allendale border, there is a grade crossing on Hopper Ave. the last time i was there, there were large incandesant bulbs and unusually short gates (this being because of the width of the road.) something that has surprised me is that whenever a train is approaching, (this may be because the track makes a curve on either side of the crossing) the lights and bells will activate and the gates will lower. once the gates have lowered, the bell stops and the lights continue to flash.
about ten seconds after the original activation, there will be a whistle blast and/or the train rounds the curve. after the train passes, the gates rise. my question is that why at most crossings (and not at this one) is a whistle blast heard long before the signals are activated and/or the gates lower? is this just something that varies from rail line to rail line? there is nothing wrong with this, just me being a little curious.
as always, any feedback is welcome.
