You could also say that 2 out of three people who were stuck by trains lived.
So, statistically, it would not be unusual to be struck by a train 3 trains before you die. Unless, the injuries sustained by the first stuck by a train, make it less likely to survive a second struck by a train.

The MTA has a web page about it
A few years ago, I was waiting for the Q train at 7th Ave in Brooklyn. I was in the middle of the platform and when the train was pulling into the station it screeched to a stop. After a long time an announcement was made that it was stuck and we were given some sort of transfers get on another train.
Later that week I had dinner with my in-laws. My Mother-in-law asked me if I had trouble getting to work because her train was stopped as it entered the 7th Ave Station because someone jumped in front of it.
So, I actually think that the 47 people that died when they were struck by trains planned it that way.
