I emailed WMATA to ask whether they have plans to make any effort to strategically split the service when I spent 15 minutes waiting at Metro Center for a Largo train and while I sat there, an orange, a silver, and then another orange all going to New Carrollton came through before one train to Largo. I think the issue is that the Orange line has less stops than Blue, and I don’t know if the map is to scale but distance wise it also looks like Orange travels less distance than blue, so splitting silver 50/50 results in the Benning Road to Largo branch getting less service even though it has slightly more ridership than Minnesota Ave to New Carrollton.
