Metro: Must all escalator stairs at the metro station be replaced at once?

The ongoing escalator renovation at Rautatientori metro station in Helsinki is causing considerable disruption to passenger movement. The project is slated to last for months, affecting the city's busiest metro stop. Trains will not stop at the station during this period, creating significant travel challenges for commuters.

A reader has questioned the necessity of renovating all escalators at the station simultaneously. They propose a more phased approach, suggesting that escalators could be renovated and installed in pairs. A construction site fence could be erected between the pairs, allowing two of the four available escalators to remain operational. This would maintain some capacity, especially if passengers are advised to use alternative stations like Kamppi or University of Helsinki during the renovation.

The reader believes that maintaining the capacity of at least two escalators would be manageable, particularly with advance communication to passengers about the disruptions and alternative routes. This suggestion aims to mitigate the impact on daily travel for thousands of commuters.
