Metro Rail will operate modified, single-track service on its surface section Saturday to accommodate ongoing work to restore vehicular traffic to Main Street.

The Niagara Frontier Transportation Authority said Metro Rail above-ground service will operate on only the outbound track between 7 a.m. and 5 p.m. The inbound track will be closed as crews work on demolishing the former Theater Station.

As a result, passengers will be asked to transfer to another train at Fountain Plaza Station operating on the outbound track to continue their trip.

Authority officials said minor delays may be encountered.
