PHILADELPHIA (CBS) – SEPTA announced Thursday that shuttle bus service will replace rail service along the Manayunk/Norristown Regional Rail Line on Saturday and Sunday.

Officials say, due to track and signal work, shuttle buses will be used between Elm Street Station and Wissahickon Train Station on March 23rd and 24th.

Officials report, buses leaving Elm Street Station will stop at Main Street, Norristown Transportation Center, Conshohocken and Spring Mill Stations and Wissahickon Train Station.

Outbound Manayunk/Norristown Regional Rail Line trains will go as far as Ivy Ridge Station, say officials.

Trains will leave from Elm Street Station 32 minutes before their regularly schedule train times and will leave from Wissahickon Train Station at regularly scheduled times.
