London Underground stopped in the tunnel announcements
I just got back from London, and on the Underground, every time the train was stopped in the tunnel for more than 30 seconds there was an automated announcement: “this train is being held at a red signal and should be moving shortly. We apologize for the delay” or something like that.
Small touch, but it adds to how professional the system feels. Wouldn’t mind if we started doing that on the B and D lines.
