(1) About halfway between Downtown Crossing and State (orange line northbound), there is a yellow-over-red signal. What does it mean? There is no diverging route anywhere near here.
(2)I see several white lights. I've noticed them on the Red & Orange lines. They're behind a fresnel lens, so they signal something. They usually face away from the oncoming trains, like the one in the picture below. The below photograph was taken at Charles facing Park Street. Based on my observations, the light is ON most of the time. When the light turns off, a train arrives at from Park Street abour two minutes later. The light remains OFF while the train is in the station, but turns ON before the train has completely left the station. And the cycle repeats. All the other lights of this type have a similar behavior. Inquiring minds want to know.
