White substance that impacted CTA Red Line commute ID'd as baby powder

CHICAGO (WLS) -- CTA Red Line trains bypassed the Addison stop for several hours Thursday morning after passengers noticed a white substance in a train car and self-evacuated at the station.

Chicago police and fire responded to the scene around 8 a.m. After an hours-long investigation, authorities told ABC News the substance was identified as baby powder and there was no threat to the public.

Buses were made available to shuttle train commuters between the Sheridan, Addison and Belmont stations during the investigation.

CTA officials recommended the No. 22 Clark, No. 36 Broadway, No. 8 Halsted, No. 147 Outer Drive Express or No. 151 Sheridan buses as alternates.

Normal Red Line service was restored around 11 a.m.
