It is also warning Brown Line customers to plan for extra travel time due to weekend track closure between Kimball & Western.The Air & Water Show takes places along the lakefront from Oak Street Beach to Fullerton from 10 a.m. to 3 p.m. both days.People taking the Brown Line are strongly encouraged to plan for an extra 15-20 minutes of travel time due to the temporary suspension of rail service between Kimball and Western stations for scheduled track work.
