(Chesterton, IN) - The South Shore commuter line is reducing the speed of its train because of the extreme heat.

Officials with the Northern Indiana Commuter Transportation District, which operates the railroad, said maximum speeds will be decreased between South Bend and Ogden Dunes to minimize any heat related damage that might occur to track and overhead wire.

"Passengers please be at boarding stations on time in the event delays are less than expected," NICTD officials said.

An extreme heating warning for the area is in effect until 7 o’clock this evening.
