If Washington were to do it then presumably it would have to run remotely with driver changeovers somewhere on the route or possibly interwork with the 50 in Durham?
If interworking patterns change they could have the 50/X20 interworking at Durham.
On current timings the X20 leaves Durham at xx:22 towards Langley Park, the 50 arrives into Durham at xx:04 which would currently give you 16 minutes layover between operating the two.
