Chicago’s Metra testing air quality in train cars, downtown terminals

On November 16, Metra in northeastern Illinois began testing the air quality onboard some passenger cars and at downtown terminals. Recent questions were raised about the level of diesel emissions on downtown platforms and trains. While Metra trains are in full compliance with all Environmental Protection Agency standards, additional testing conducted on a system-wide basis will provide a more detailed picture of total air quality.

In order to fully
investigate the issue, Metra has retained an independent firm, Carnow, Conibear
and Associates, to test the quality of the air at downtown Metra terminals and
onboard passenger coaches.
