Major infrastructure upgrades to the Barrie line are affecting GO Train service this weekend.

Both Saturday and Sunday, crews will work to replace the tracks at the McNaughton Road crossing near the Maple GO Station and the Dufferin Street crossing north of King City GO Station.

As a result, buses will replace trains north of the Rutherford GO Station.

“This work can only be completed when trains aren’t running, so we’re doing the work over the weekends, which aren’t as busy, to minimize the disruption,” GO Transit said in a notice on its website.

Buses will also replace trains north of the Aurora GO Station on the weekend of October 27 and 28. Trains will run between Union Station and Aurora GO Station.
