The reason why it was considered that this section of line, which is
situated far north of the polar circle (at 68° latitude in the regions of
eternal .snow, almost at the same degree of latitude as Alaska), should
be dealt with first was, partly, that at the period in question this section of
the State Railways had the largest regular traffic of the whole of the
State railway system, and also the circumstance that it would be necessary
in the immediate future to make a considerable increase in the
traffic-powers of this section, in consequence of the growing transport of ore,
concerning which an agreement had been entered into between the Swedish
State and the Mining Companies concerned. The work, both as regards
the installation of the power-station and also with regard to all the other
details required by the electrification of the section of line in question, is
now being carried out and it is expected that the line will be opened for
this traffic in the beginning of the year 1915.

The Power-station at Porjus, Lappland.
The electric power will be obtained from the Porjus waterfalls, in the river
Stora Lule älv. These falls consist of four separate falls, of which the largest
is the so-called Routikårtje, which consists of two waterfalls lying one
immediately below the other.
The engine-room of the power-station in which, for the electrification of the
line, there are being mounted turbines of together 50 000 h. p., and made for
a tension of about 4 000 volts, consists of a chamber blasted into a hillside and
