"The new station included a modular design, to accommodate an increasing station population, and an adjustable elevation,
in order to prevent the station from being buried in snow. In a
location where about 20 centimetres (8 in) of snow accumulates every
year without ever thawing,[7][8] the building's rounded corners and edges help reduce snow drifts."
