I’ve never ridden it or even seen it in action. But I plan to ride it when I visit the Hub City next month for the first time (other than passing through a couple of times on the way to Canada).
Motor: I think most of the system has been rebuilt since I was there 30 years ago.
The 4 main rail lines all cross in the center of the city.
The Green line uses the oldest subway tunnel in North America (Tremont Street) and runs street cars. It branches out and does interesting things.
The Blue line used to be a streetcar line; they still use the old street car loop in downtown and have had to buy short rapid transit cars. When I rode it was 3rd rail down town and under the river, then overhead wire. Goes near the airport.
The Red line runs from Harvard (Cambridge) to Quincy. Has the largest cars.
The Orange line used to be the El, but I think it’s been all replaced.
The Mattapan-Ashmont line is at the end of the Red line, but I think it’s being closed for rebuilding.
There are also Diesel rail lines and buses.
The subway line in Boston (It’s called the “T”) is incredible. Cheap, safe, efficient, fun… The Green Line is my favorite and some of the old stations downtown are fantastic.
The Green Line is actually kind of multi-branched. There is still some street running (not a whole lot). Perhaps the best or most interesting is the Riverside branch, which is an old Boston & Albany line once used to turn trains from South Station and also as a suburban commuter line – the stations used date from that era (except Riverside!).
Overall, as Green Bay said, the system is really fine. Enjoy it!
Be sure to go to one of the major stations (Park Street or Government Center )and pick up an all day pass. Then you don’t have to worry about the extra nickel.
