I have to give the red line 4 stars. Yelpers giving the Red line 2 and 1 star are out of their minds. Did you guys ride other trains like the blue, orange, silver and the green line? I really doubt it, because if you did, you would have never give the red line 2 or 1 star. Take a trip to Nyc and see how you like their trains? How crowded and nasty their trains look. The red line is actually the best line. It's not crowded, don't stink bad like the orange line. Check out my review of the orange line. You will understand what I am talking about. It's not a trolley and moves faster than the green line. You can read my review of the green line if you need additional information. You can feel the ac because it's less crowded. The stop I hate is downtown crossing. You will see a lot of black people all the sudden. The last stops of the red line are bad like Fields Corner and Ashmont. The black neighborhoods of Dorchester, Mattapan and Roxbury are there watch out it's very dangerous. Braintree is better. Truereview here to tell you the truth.
