Just out of curiosity, how many PA-4 (or other PA series cars) have orange LED destination signs mounted inside the windows? I'm talking about the signs inside the cars that display the entire destination i.e. "Journal Square" that someone on the outside can read, and not the red LED's ABOVE the windows that only say "JSQ", "WTC" etc . An example would be the one on car #838 (saw it a few nights ago). I've also seen red LED signs that display the entire destination, but don't recall the car number(s). Thanks.
