Back before they removed the signals from the Lowell Line, the general way signals seemed to work was that if there was a train in the current block or nearby block, the signals would light up. Otherwise, they'd be dark. That still seems to be the way they work in most spots where there still are signals.
Aside: Although I notice that sometimes signals closer to the train will shut off before ones further away. Like the signals on either send of Anderson Station. If a train is leaving to the North for example, the signals North of the station will shut off before the signals at the South end. It's like there is a smaller block embedded in a larger block, rather than the blocks just being lined up in a row up the line.
But anyway that's not what this post is specifically about. Reading also has lots of signals around. Signals to the North of the station seem to always be dark, unless a train is coming. But the signals on the South end of the platform, and the signals less than a mile to the South of that (adjacent to Market Basket), always seem to be lit up, and red, 24 hours a day. Just to the south of those Market Basket signals, theres another small, single signal right at New Crossings Road that only lights up as a train is going by,
I'm confused by the logic of how all these signals work, and why they don't seem to be consistent!?
