I saw the LIRR news, and while that's certainly the worst it's ever been, it's not the first time, nor the second (nor third, etc.) that the transfer point through Jamaica station has been fubar.

I used to commute on the Port Washington line. My boss lived in the same neighborhood as me, and we would often travel together. We had several times when we felt quite lucky for being on the "orphan line" that wasn't affected by problems at Jamaica.
