A walkout by SEPTA Regional Rail workers could begin as early as 12:01 a.m. Saturday, the Philadelphia Inquirer has reported.
The publication said a Regional Rail strike was "increasingly likely."
If it does happen, the strike would impact all 13 lines on SEPTA’s Regional Rail service. It would be the first strike in 31 years, the Inquirer said. Bus and subway service would not be impacted.
Earlier this month, SEPTA Regional Rail engineers authorized a strike. SEPTA's Regional Rail engineers have been working without a contract since 2010; the electricians have not had a contract since 2009.
