There is a rooftop terrace on top of the station, accessed by lift from the subway by Platforms 12 and 13, with views over the city and to the Bernese Alps.

Amid projections of dramatically increasing passenger numbers, plans for a major expansion and development of Bern Station, largely focusing upon new underground areas, were mooted during the 2010s.

Swiss Federal Railways, Regional Bern-Solothurn, and the city of Bern are the key backers behind this development.

On 26 June 2017, authorisation to proceed with the planned station expansion was issued and construction activity commenced during the following month.

As a consequence of this decision, Bern experienced a construction boom promptly thereafter; this work was undertaken with the goal of providing the various amenities and local infrastructure in line with its new-found status.

Amongst the projects commenced was a sizable railway station, which was built to accommodate the large volume of local, regional, and international traffic which had been anticipated.

Reportedly, projections have been produced which anticipate that, by 2030, passenger numbers using the station are set to rise to between 260,000 and 375,000 people per day.
