Original post: Monday’s summer-like weather has prompted CSX to issue heat restrictions for trains traveling on the Maryland Area Regional Commuter Brunswick and Camden lines.
CSX operates the Brunswick and Camden lines on CSX-owned tracks. The Brunswick Line carries passengers between Washington and points north and west, including Frederick and Martinsburg, W.Va. The Camden Line connects Washington and Baltimore.
The heat restrictions are in effect until 7 p.m. and means trains will operate at 20 mph less than normal speeds, to a minimum of 40 miles per hour. The Maryland Transit Administration estimates that delays will range from 10 to 15 minutes.
