The Walnut Creek BART station was shut down for several hours Wednesday and impacted the evening commute while police negotiated with an unstable man hanging from a ledge.
Emergency crews were able to get the man to come down after 5:15 p.m.
Authorities said the incident started at about 1:30 p.m. and prompted BART officials to halt service at the Walnut Creek station.
Pittsburg/Bay Point trains were turned around at Lafayette and SFO-bound trains at Pleasant Hill until the situation was resolved.
The transit agency also set up a bus service between Pleasant Hill and Lafayette for passengers.
