WMATA does not use CBTC, it uses audiofrequency tuned track circuits relaying train control via cab signals. Thus while CBTC has no fixed block length and headway is limited solely by the performance of the rolling stock, WMATA is constrained by fixed block lengths and the time required for a train of a given length to clear the longest block. |
