Sunday, Dec. 17, at the Greenbelt Station, Metro will begin full implementation of bus transfer lights to ensure customers can make a reliable connection to their bus on low-frequency routes. Metro first tested the system in July. When a train approaches the station during off-peak hours (9 a.m. – 2 p.m. and 7:30 p.m. – midnight), a strobe light will signal to bus operators to wait up to five minutes before departing so that Metrorail customers have time to make it from the station platform to the bus.
