I thought that study said 7 minutes savings was if they don’t have a third rail because it would just catch up to the train in front.

The only logical way to shorten the runtime to Dulles is to build a track that would bypass the 4 Tysons Corner stations and upgrade the signaling system to allow closer headways, As built the Silver line is limited to 19 train per hour.
