is reached from Kristiania by a rail journey
via Drammen and Vikesund, and a steamboat
trip along the lake —and Bergen. The central
section—-Gulsvik to Vossevangen, or Voss—
opened in 1907, demands most attention, as
it crosses thø great water-shed of the Lang
Mountains, passing through some of the wildest
mountain tracts in Norway, far above the
tree limit, in the region of eternal snow. As
regards the greatest elevation attained—4,268
feet at Tauge vand—the railway is surpassed
in Europe by the Brenner Pass and Arlberg
routes, and in America by several trans-
continental railways. But it should be pointed
out that even the Southern Pacific crossing in
the Sierra Nevada, with its maximum elevation
of about 8,200 feet, does not
rise above the level at which
firs, the hardiest of trees, cease
to occur; whereas the Bergen
railway, owing to its much
latitude, leaves trees behind
at an elevation of about 2,000 feet. The

the country with a thick blanket of fine hard
snow, packed tightly into every hollow and
crevice by violent gales, rendered the con-
struction of the railway, especially at the
higher altitudes, a very difficult task indeed.
In the mountains snow falls even in June,
and during a cold summer the snowdrifts and
the ice covering the lakes do not melt at all.
In laying the line, however, the engineers were
careful to raise the road-bed, where possible,
above the general level of the ground, so that
the winds might assist in the task of keeping
it free from snow. For 12J miles the moun-
tain section of the line has been covered in
with snow-sheds, and 28 more miles are shel-
tered by snow-screens. The section is only
62 miles long, so that if the 9| miles of tunnel
also be deducted, it becomes evident that only
a very small proportion of this section is left
entirely unprotected.
As long ago as 1870 a scheme was put
forward for running a railway across the
“ Great Mountain.” At that
time the sea afforded the only History,
means of communication between Bergen and
Kristiania. Not even'the roughest of roads
