I have only encountered 2 train riders in 5 years in S. Florida, both times I trespassed them and escorted them off the yard. SAO's down here dismiss 99.99% of trespassing cases anyways. Our problem is when the train stops in certain areas, we get hit bad, last time 12 units were opened and emptied, before the locals and we got there. That and the homeless encampments that spring up on the mainline.
Here in Florida we are appointed by the Governor and have Statewide jurisdiction, both for FSS and CFR cases.
