Normal service resumed Tuesday morning at the Peachtree Center MARTA station after a fire under the train platform shut the station down Monday afternoon.

The fire was one of several, both inside and outside of MARTA stations, that plagued transit riders throughout the day. While rail service resumed Monday night, the Peachtree Center station was closed for investigation until Tuesday morning.

A bus bridge between the Five Points and Civic Center stations was terminated just before 8 a.m.

A fire under the Peachtree Center platform sent smoke into the station, which was evacuated as a precaution, MARTA spokeswoman Stephany Fisher told AJC.com. She said the fire was related to electrical issues, but further details were not available.

Once power was restored to the tracks, Peachtree Center remained closed but trains were traveling through the station without stopping. The Civic Center station was also closed until later Monday night.

The shutdown caused significant delays throughout the transit system, according to the agency.

That wasn’t the only fire to affect public transportation Monday. Small brush fires were spotted near the West End, Ashby and Chamblee stations, Fisher confirmed. That prompted trains to be held at those three stations in addition to Five Points and West Lake until Monday afternoon.

Smoke was reported in the tunnels and on the tracks by riders at several stations. It’s unclear what started the brush fires.
