Are there any that were not completed but are just stubs.

If you use the pure definition of the term, no. There is however a cut and cover equivalent at the south end of the Pentagon station for a future route along Columbia Pike.

SBJ, Thanks for that although I thought that there might have been more which would have been closer to actually being built when the system was being planned.

There is one more that I forgot to mention. A cut and cover equivalent is at the north end of the Glenmont station to accomadate the extension of the B Route end of the Red line. The one on outbound track B1 is clearly visible from the station platform. The one on inbound track B2 is at the point where Glenmont Yard lead track 2 curve to the east about 800' north of the station.

That is a cool map, John. Do I see another stub at Largo?

Yes, they are on the surface, they are there for turnouts to extend the route further east.

You might find this of interest as well.
