The South Shore Line plans to periodically bus weekday (Monday-Friday) passengers between Carroll Ave. and the South Bend International Airport while they upgrade track and segments of overhead wire between Michigan City and South Bend. The temporary busing periods will occur Monday, Aug. 12, through Friday, Aug. 16. During this time, weekday train service between Carroll Ave. and South Bend will be suspended, with buses arriving and departing with passengers to match the published Monday-Friday train schedule between Carroll Ave. and South Bend. Busing availability at the South Bend Airport will be limited, therefore westbound passengers are encouraged to board at Carroll Ave. Station or other western stations. Bus service to and from Hudson Lake will not be available during this time. Hudson Lake passengers are encouraged to board at the Carroll Ave. station. Additionally, the following trains operating exclusively between South Bend and Michigan City are canceled during busing: Westbound Trains 422 & 424 Eastbound Train 401 South Bend passengers will board buses located just north of the train platform at the South Bend International Airport. No bikes will be transported via bus for Trains 6 and 11 during this time.  Train service between Michigan City and Chicago will operate as scheduled. Delays may occur due to the busing.
