SL Explores Alternative Solution for Red Line Delays

Public transport operator SL is exploring an alternative solution to get trains running more normally on Stockholm's Red Line, which has been plagued by a persistent signal failure.

Jon Sundh, head of SL's technical department, stated that the company is working on two parallel tracks to reduce the risk of further delays. "We are working in parallel on two tracks to minimize the risk of it dragging out," he said.

Despite ten days of intensive troubleshooting and the replacement of about a dozen faulty components, SL has yet to identify the root cause of the signal malfunction. While the investigation continues, SL is simultaneously developing a temporary fix. This involves isolating the section of the system where the fault is occurring.

"A change is being made in the signaling system that allows us to disregard the specific switch that is causing the problems," Sundh explained, indicating a workaround rather than a permanent repair.
