Pennsylvania this week approved an updated long-term transportation plan that includes the $2 billion project to replace all 218 of SEPTA's Silverliner IV rail cars. But this is such an acute need that even without the funding in place, we're going to move forward," Busch said. SEPTA said in July that 98% of its Regional Rail cars were available for service following the issues last summer. The agency is also looking to leased and purchased rail cars from other transit agencies to give it additional flexibility. Earlier this year, SEPTA leased cars from Maryland for $2.6 million as it completed federally mandated repairs to the fleet.
