Well there aren't any more trolleys The two last pictures there are the most recent One of them is on the Williamsburg bridge in 1995 It was blamed on the motormans fatigue and he probably fell asleep running into a stopped train There have been what they call grade time signals installed there to prevent that now If a train goes above 25 its emergency brakes are tripped and if a train gets too close the same thing happens.
The other one is on the Lexington ave line in 1991 The motorman was going 50 and the switch speed limit was 10. They have installed grade time signals there also.
The worst subway accident was in 1918 at Malbone street There was a strike going on and an inexperienced motorman hit the curve at 35 MPH on a 6 MPH limit curve. They don't use that tunnel anymore as the FRanklin shuttle only uses one track there
