This has been a terrible week for commuters who rely on Penn Station. A NJ Transit train derailed just outside of Penn Station on Tuesday which screwed up NJ Transit, Amtrak and even Long Island Rail Road service for two days. And then an Amtrak track derailed yesterday. Now we're hearing that Amtrak trains at Penn Station are delayed due to "switching problems"... and NJ Transit riders get to enjoy these high-tech signs... well, high-tech if the equipment is a Sharpie marker.
