Vomitola points out that Billerica is not actually where I thought it was– it’s near Lowell, and is served by commuter rail. When I said “Billerica” I should have said generally anywhere out past Revere, which is not at all where Billerica is.
Plus, I totally forgot about commuter rail. It’s good. We need more.
I went to Beverley once on the commuter rail. Trains run too infrequently for my taste except during rush hours… hence the name “commuter.” It is good though, and it is useful. It’s better maintained than the regular subway, too, which makes regular-subway riders kind of jealous– newer trains. Functioning air conditioning. Bigger trains, since it’s a full-on railroad. Anyway, it would be cool, in my fantasy world, not to have to switch trains, and for trains to go really far. The DC Metro is basically my vision of a proper subway system– I know it has flaws, but it’s got a lot of advantages.
