If you look at the map carefully, you see that Broad Branch joins with another branch just before it comes to Rock Creek. This branch currently runs beside the Netherlands embassy and stops. But on the old map you can see this branch goes all the way to Tenleytown. That means the tunnel system of the Broad Branch area is connected to the subway tunnels (subway is at Tenleytown)
