Expect delays throughout Tuesday afternoon and evening on the Camden and Brunswick lines. CSX has issued heat orders starting at 1 p.m. and continuing to 7 p.m.

Trains on both lines will operate 20 mph below their normal maximum speed, but they can travel at least 40 mph. The Maryland Transit Administration says delays can range from 10 to 15 minutes.
