Does anyone remember when they had watchmen at that crossing? Everytime a trolley came to the crossing the watchman had to pull a big lever. Failure to do so the trolley track defaulted to a derail.
Instead of a standard diamond the trolley tracks are raised up an inch or two so that the weight rests on the flange instead of the tread. Only one flange per truck is riding over the rail at a time so there is no derailment risk. Flange riding diamonds eliminate the wear issues for trains on the main track seen with standard diamonds. Trains on the crossing track must proceed at low speed however.
cool

not the only one in the country, but indeeed rare. another exists on the TECO trolley in Tampa (at least).

The TECO crossing is not part of a road grade crossing.
