According to Lennart Helsing, the Administration's press officer, a second track should reopen Wednesday morning though he can not say exactly when. Helsing said the remaining two tracks would likely open later this week.
The early morning derailment is still causing major headaches for commuters with cancellations, delays and detours affecting thousands.
The accident occurred about 6:30 a.m. when a cargo train jumped the tracks, striking and damaging a pillar. According to the Transport Administration, an accident investigation will take three months to complete.
