Weekday trains scheduled for midday hours are not running on the Gladstone Line this summer, due to a tie-replacement project. Buses are running between Summit and Gladstone on a similar schedule, but the buses leave Gladstone earlier than the trains they replace. Weekend trains are not affected this year. The outage began on June 20th and will continue until sometime in August. When service was suspended during previous summers, the trains returned by the end of August, in time for the beginning of the school year.
