This looks like a commuter train. I haven't seen that reported anywhere. I'm sure the muzzies aren't precise enough to be able to target a train, but they probably had a pretty good chance of getting commuters and it's clear that this is meant to make Israeli work/economic life impossible.
I believe MSNBC showed clips of it early this morning.
