Why does MTA keep these little stations in operation? Stops like Garret Park, Washington Grove, and Boyds for example. It seems these stations support about 20 people grand total on a good day. And they're only a few minutes from a major stop like Gaithersburg, Kensington, or Germantown. You can almost see Gaithersburg from Washington Grove. By doing away with these stops, you get longer high speed stretches and can shave about 10 minutes off the schedule. Less fuel due to less starting up from a stop. And they wouldn't need to waste money on keeping the stations in operation. I'm all 5 people that use Washington Grove would be sad to see it go. But really? It's not a bus.
Garrett Park sees 54 riders a day, as of 2013. 54 is pretty decent seeing as only 5 trains each way a day stop there. That means on average 11 people get on or off each train that stops there.
Washington Grove sees 44 daily riders, with 4 trains each way. Again, that's an average of 11 people getting on or off each train that stops there.
Boyds only sees 16 daily passengers though, which is an average of 4 per train. This one I might agree with skipping, but it consists of little more than two short strips of asphalt and a bus shelter, so it hardly costs anything to maintain. The MTA probably keeps it open because there's been a station there since the B&O days, and it's less of a hassle to keep it open as a bare-bones minor station served by a handful of trains than to try and close it. Plus I could see it becoming more heavily used in the future if growth around Germantown keeps up.
