For a second day, MARC trains will be delayed because of excessive heat.

The Maryland Transit Administration said Wednesday that afternoon trains running on the Brunswick and Camden lines would operate 20 mph under the maximum authorized speed between 1 p.m. and 7 p.m. MTA said that reduced speeds would lead to delays between 10 to 15 minutes.

The slowdown was ordered by track owner CSX Corp. Inc. to avoid problems with rails bending or kinking in the extreme heat. A similar order was issued Tuesday.

In addition to concern about the CSX rails, the Penn line, operating on tracks owned by Amtrak, could also be affected by the heat. Maryland Secretary of Transportation Beverly Swaim-Staley warned that the performance of locomotives, air conditioning in passenger cars and catenary lines carrying electrical power on the Penn Line are pushed to the limit in excessive heat, and she cautioned customers that heat-related issues have the potential to create delays throughout the system.
