Why Single Trolleys During Rush hour?

Postby jumbotusk » Mon Aug 30, 2004 9:36 am

Many mornings in Brighton or Brookline I see single trolley trains on the B or C line during rush hour. Why? Even when there are double trolley trains, they are packed to the brim. Do they run just one for fun?

Can't you get greater capacity by running 1 double train instead of 2 singles, because of signal block spacing?

Sometimes that happens when a trolley has a problem enroute, and has to be cut out of a two-car train, resutling in a single.

More often, however, it's a personnel shortage: either an operator didn't show up, called in sick at the last minute and couldn't be replaced in time, etc.

The opposite happens on the E Line. You wait a long time for the train when it comes its two car and then you get on, its air conditioned, you get a great seat, and when you think its a perfect ride... You get stuck at Brigham Circle so other trains can catch up. You wait almost 10 minutes and when you get going again all the other stops are packed.

I don't know what the current car requirements for the Green Line are, but most times there are a half dozen or so single "RAD" (Run As Directed) cars assigned during rush hours. They do just that - run as directed by a starter or inspector.

In the past, it wasn't unusual for the T to couple a few of the RAD cars to scheduled two-car trains to form three-car consists, but I haven't seen many of them out there recently because fewer cars are required during the summer schedule. Perhaps the RAD cars are running as singles for now, and used to cover gaps in service (which is exactly what they're intended to do).

Demand and thus car requirements will be increasing as summer comes to an end and the school season resumes, so the single RADs may once again be used to form three-car consists with the fall rating change in September.

Why Single Trolleys Run During Rush Hour

Correct on the RAD's (Run As Directed) which a majority are out of the Res. Also they will drop a second section of the trip for numerous reasons, lack of operators, equipment or run two singles to cover a missed trip. Hope this helps :wink:
