It seems Wheelock is VERY popular for MBTA’s stations. Besides that, in Brockton we have three commuter rail stations, all of which have no alarms. The closest to our house is the Campello station, and then there’s the Brockton station near the Bat Bus terminal. After that comes the Montello station. The latter two stations both have pedestrian-only railroad crossings. I recall they were going to install gates for them, but wound up only putting up the crossbucks, red lights and bells. (One day after school I passed by the Brockton station just as a guy from the railroad signaling division was testing the crossing signals; I figured something was going on when I heard the crossing bells go off at 2:30, which is 20 minutes before the next train approaches.)
As for the Red Line, unlike the Commuter Rail, the fleet they use is the same for both ends. They have the older subway cars made in the late 1960s-late 1980s, and the newer “Bombardier”-style cars made in 1994. I also got to ride on one of the newer Siemens-manufactured Blue Line trains. They seem to have been mimicking the Red Line Bombardier trains!
