NEW CANAAN — Metro-North will provide substitute busing for select trains Friday through Sunday between New Canaan and Stamford.

Buses are being provided because of a PTC (Positive Train Control) Infrastructure Project that is under way. Buses to Stamford will operate about 15 to 20 minutes earlier than the scheduled trains, Metro-North said.
