In a rather low-key announcement, SEPTA says that starting Dec. 7, it would be discontinuing the use of "Passenger Advance Lights" on the Norristown High Speed Line.
If you've never ridden the NHSL, these are lights on the platform that can be triggered to alert the operator of an incoming railcar that someone is waiting to board. They're sort of irrelevant at major stops, since most likely there will be people getting off anyhow. But at minor stations, or late at night, these would allow riders to be assured the next train would stop for them, allowing them to stand further back in the shelter and not have to worry about flagging down the next train.
Now, SEPTA says trains will only stop for "visible passengers." (Or, of course, if someone is getting off, which they will signal the driver sort of like on a bus.) This means riders waiting to board will have to be more vigilant to watch/listen for the incoming train. It's not the end of the world...in fact, being visible to the operator is a pretty standard way to get a bus or trolley to stop. But NHSL trains are faster than most buses or trolleys, and can sneak up on a station pretty quickly.
SEPTA offers no explanation for the shut down, although one can imagine it's to save on operational and/or repair costs. (Or maybe there are pranksters running around turning them on?)
Are there any other rail services in North America that use a similar system? I know there are obviously rail lines with flag stops, but I'm talking specifically about the use of a light to trigger a station stop.
