Wire problems suspended all train service on the Metra Electric District line for about four hours Saturday night.

Inbound and outbound trains were initially stopped about 9 p.m. between 111th and 115th streets due to problems with the overhead wires, according to Metra.

Inbound train No. 342, scheduled to arrive in Chicago at 8:27 p.m., was stopped near 69th Street and was delayed more than 130 minutes, said Metra spokesman Michael Gillis. Train No. 144, scheduled to arrive in Chicago at 9:47 p.m., was stopped near 51st Street.

Passengers were transferred to CTA buses as crews worked to fix the problem. Trains were on the move with “extensive” delays as of 1:10 a.m., according to the transit agency.

No injuries were immediately reported, but firefighters removed 64 passengers from one train, according to Fire Media Affairs Chief Joe Roccasalva. He said a fire was not started on the tracks or on a train, but electrical problems with the overhead wires may have caused sparks.
