Overview
- NS reports about 700 carriages required maintenance this week, roughly 300 more than normal.
- Fewer trains ran on seven routes during the week due to limited available rolling stock.
- Traffic control locked many track switches to prevent damage in subzero weather, which hindered routing to depots.
- NS says trains are vulnerable to cold, with heaters malfunctioning and retractable boarding steps freezing.
- After initially projecting a week to catch up, a spokesperson said services should return to the normal timetable by Friday.
