The sudden crisis that began last week is going to have long-term repercussions for SEPTA. The cost of repairs, including labor and materials, should be covered by Hyundai Rotem's warranty, but it is unclear if some of the ancillary expenses, like lost revenue, refunds and overtime, will be covered. Knueppel declined to estimate what the disruption could cost the authority, but said it would be in the millions. Just leasing the additional railcars is costing as much as $8,000 a day for a five-car set. The full cost hasn't been tabulated, Knueppel said.
