TORONTO - There were a few speed bumps for GO Transit commuters Thursday morning.

An equipment problem on the Milton line caused the Milton 6:23 train to arrive nine minutes late at Union Station.

On the buses, an equipment issue meant the Oshawa 6:05 to York University operated as an express from Oshawa to Unionville.

Passengers between Oshawa and Unionville were accommodated on the Oshawa 6:35 bus trip.

And a picket line set up by striking York Region Transit workers at Richmond Hill Centre disrupted service on GO bus routes 40, 51, 52 and 54.

Passengers were advised to board on Yonge Street between Garden Avenue and High Tech Road.
