While that worked out great for you, I can imagine it conceivably could cause problems if other passengers decided they wanted off too, and possibly delaying the train while they scrambled for their belongings. Or other passengers maybe asking to be left off at some other unscheduled stop…or if someone got off at an unscheduled stop, and suffered some mishap, it could be a legal liability…far-fetched, perhaps, but still possible…The train crew can be surprisingly accommodating. One time I was on a spectacularly late Cardinal heading to NWK. My original plan was to catch an NJT back to Metropark where my car was parked. It was so late that by the time it got to NWK I would most likely miss a connection to 67 even, forget about NJT. I mentioned this to the Conductor asking permission to stay on to NYP. Surprisingly he said, we were going to be on track 1 through Metropark due to track 2 out of service. He'll see if he can just let me off there. And lo and behold, the train stopped briefly at Metropark to let me off! That saved me many hours of hassle and got me home early enough so that I could get several hours of sleep before heading off to my work desk at home for a late morning meeting.
