The federal government is giving Metra more than $5 million to help reduce toxic emissions. This comes a year after a Chicago Tribune report that found high levels of diesel exhaust at Ogilvie train station and in some commuter rail cars.

In a statement, U.S. Sen. Dick Durbin, D-Ill., said reducing train emissions will save Metra fuel and help limit commuter exposure to harmful air pollution.

The money was approved by the Chicago Metropolitan Agency for planning. It will be used to replace engines on two trains and incorporate technology that will help engines shut down and start up faster on another 24 trains.
