SEPTA commuters started their day even earlier on Wednesday as 120 regional rail cars remain sidelined.

The Trenton and West Trenton lines continue to run on an "enhanced" Saturday schedule with less frequent service, but an extra train that will run earlier than normal to start the day.

"After Tuesday's morning rush hour we reviewed everything that happened and we actually made some adjustments" to all of the lines on an enhanced schedule including the two lines start in New Jersey, spokesperson Heather Redfern said. "It's a very fluid situation for us."

Six trains that reached capacity and were running standing-room only had to skip stations, including one each at Trenton and West Trenton.

"As you get closer to Center City that's where they start bypassing stations across the board," Redfern said.

Redfern said more riders were expected for Wednesday's commute as many users extended their Independence Day vacations by a day on Tuesday.

"We're still stressing that people should try to find an alternate means" into Center City Philadelphia, she said.

Talks with NJ Transit and Amtrak are ongoing to borrow equipment for use on all SEPTA's regional rails.

"We don't even know if that's even a possibility, It's something we're discussing and reaching out to other agencies," Redfern said.

Lines on the enhanced Saturday schedules include: Trenton, Manayunk/Norristown, Media/Elwyn, Lansdale/Doylestown, West Trenton, Chestnut Hill East, Wilmington/Newark, and Paoli Thorndale. Lines on a regular Saturday schedule: Airport line, Chestnut Hill West, Fox Chase, Warminster, and the Cynwyd line.
