Updated 30 January 2021 6.14pm: Train services are returning to normal.
Train services are returning to normal from 6pm on Saturday. I, P and K trains stop at all stations again and return to their scheduled service. Train services are expected to run as normal also on Sunday.
However, there may still be delays to northbound R and Z trains.
The disruptions were due to an electrical fault between Tikkurila and Oulunkylä. The fault was noticed early on Friday morning.
