I believe Alewfie still has the light up signs - they just dont light up.

Is it automatic on a timer, or does someone in a control center do it?The bells ring off automatically, but the line's Dispatcher can take control over them either preventing it from ringing if a train is to be held, or ringing it sending a train out at a time a trip wasn't scheduled. The "Next Train" signs at Alewife are still there, they just don't use them anymore for some reason. I was happy when I saw they're still used at Forest Hills.
Even if they know when the bell is going to ring, there's a lot of uncertainty in how long it will be until the train actually leaves. Which affects when the outbound train(s) waiting in the tunnel will arrive at Alewife.
At Alewife, these signs will also indirectly tell passengers which train is leaving first, since either Ashmont or Braintree will be listed first.
It's no fun to guess wrong when there are trains parked on both tracks. Train operators hardly ever make an announcement before they close the doors and go. There used to be light-up "Next Train" signs (and still are at Forest Hills), but they were removed a few years ago.
