They're doing exactly as he said -removing the automatics (intermediate) ABS signals and reconfiguring the home signals to accomodate a loss of cab signals.

But starting about 10 years ago or so, the signals lit up and stayed lit. All the time. Now, I assume due to the previously mentioned signal project, the signals are dim again.Signals would light on approach of a train for many reasons. Save electricity, less light pollution, and fewer bulb replacements. Now with LED lights, the beams are more focused, they last MUCH longer and consume far less energy. There were always certain critical locations which would be lit full-time for one reason or another.
I'm all around this line pretty regularly, but I'm on Cross St in Winchester and Montvale Ave in Woburn pretty much every day. It's surprising to see unlit signals again.
So does anyone know what the whole story is in this area? Why did the signals go from sometimes lit to always lit, and now back to sometimes lit.
