Punctuality
Reliable and punctual service with trains running on time is important to increase sustainable travel by regional trains in the Stockholm-Mälaren valley. Here we will regularly report on the punctuality of the regional train services. We report on a monthly basis about the punctuality of the Mälartåg lines.
Mälartåg punctuality
January - November 2024
November 2024: 84 percent of the trains were on time in November. The decreased punctuality can be attributed to the season's first winter storm. Snow and strong winds affected both vehicles and infrastructure in parts of the rail network. For instance, on the day the first snow fell, a car ended up on the tracks, halting traffic for several hours between Stockholm and Uppsala. November was also marked by numerous track and switch failures in the Stockholm area, causing long delays that had ripple effects in other parts of the system, as well as many incidents of unauthorized access to tracks at multiple locations.
October 2024: In October, 86 percent of trains were on time, an increase of one percentage point compared to September. The major delays during the month were caused by accidents on the railway. There were several incidents involving unauthorized persons in track areas and collisions, as well as weather-related accidents, including trees falling on overhead lines due to storm winds. Additionally, slippery tracks, which caused traffic stoppages, and signal failures affected various Mälartåg lines.
September 2024: Punctuality for Mälartåg remained low during September, reaching 85%, which is one percentage point better than the previous month. Several major incidents affected punctuality for the month. A train from another operator collided with a tractor trailer near Köping, which brought down the overhead lines and caused a power outage, resulting in significant disruptions. Throughout the month, there were also several wildlife accidents and trees falling onto overhead lines, contributing to delays.
On September 27, Mälartåg faced multiple issues simultaneously: a switch failure in Flen, signal failures at several locations, and a moose collision that stopped traffic. At the same time, a train from another operator needed to be evacuated due to a powerless locomotive.
August 2024: Punctuality was generally low during the summer, despite favorable weather conditions. In August, 84 percent of the trains were on time. Many of the disruptions during the month occurred in the Stockholm area, affecting several of Mälartåg's routes. Södertälje experienced multiple signal failures, a major power outage on the line to Flemingsberg, which impacted traffic for nearly a week, as well as a fire alarm on a train that led to the evacuation of the vehicle. Additionally, accidents and incidents on the tracks contributed to further disruptions in traffic.
July 2024: Punctuality in July was 88 percent, an increase of 1 percentage point compared to the previous month. Challenges with infrastructure, as well as accidents and incidents involving unauthorized persons in the track area, caused long delays. A collision at Årsta led to a halt in traffic, and for several days there was a shortage of staff, primarily due to illness.
June 2024: 87 percent of the trains were on time, the same level as the previous month. Once again, it was mainly a number of major infrastructure incidents and accidents that negatively impacted punctuality. The biggest disruptions were caused by a fire in an electrical cabinet at Stockholm Central, which caused traffic to stop for several hours and affected several Mälartåg lines. Electrical faults at the same location, several personal accidents, and contact wire faults at Kjula also caused significant delays.
May 2024: 87 percent of the trains were on time, a decrease of 2 percent compared to the previous month. Several disruptions in the Stockholm area affected all trains passing in or out of Stockholm, leading to consequent delays throughout the Mälartåg system. Among other issues, there was a signal failure in Stuvsta, and on the same day, an accident at a commuter train station, which resulted in further delays. An electrical fault in a converter station caused a stoppage between Älvsjö and Stockholm South, and a torn contact wire at Stockholm Central also contributed to the delays.
April 2024: 89 percent of the trains were on time in April, a decrease of 1 percent compared to the previous month. The major disruptions affecting punctuality were an accident south of Stockholm that resulted in a complete traffic stoppage and a severed signal cable during track maintenance between Nyköping and Norrköping. Many cases of unauthorized individuals on the tracks, as well as a number of vehicle malfunctions on both Mälartåg and other operators, also impacted the traffic.
Mars 2024:Punctuality during March reached 90 percent, an increase of 1 percentage point compared to the previous month. Punctuality was affected by several incidents during the month. A fire in a transformer in Solna resulted in disruptions north of Stockholm, leading to subsequent delays for southbound trains as well. Additionally, a contact wire was torn between Järna and Flemingsberg, and multiple cases of unauthorized individuals in track areas throughout Mälardalen caused further delays. An accident near Nyköping also contributed to impacting the punctuality of the trains.
February 2024: Punctuality improved during February. 89 percent of trains were on time, an increase of 13 percentage points compared to the previous month. The major disruptions were due to infrastructure faults, accidents, and track maintenance, many of them in the Stockholm area. A track fault at Solna caused reductions and delays in traffic, two accidents occurred at Stockholm Södra and Solna, and cracks in a switch between Flemingsberg and Södertälje resulted in limited accessibility. Track maintenance to install a new switch at Härad led to speed reductions, affecting punctuality on the Örebro-Eskilstuna-Stockholm-Uppsala line.
January 2024: Punctuality remained low at 76 percent, an increase of 2 percentage points. The cold winter weather affected the vehicles, resulting in an increased number of vehicle damages, and the infrastructure. Several track and switch faults occurred at multiple locations throughout the month. In week 3, there were track signaling faults south of Stockholm during the morning rush hour, causing train queues in both directions, as well as at Kolmården.
