The 'Pilatus Railway' or 'Pilatusbahn' (PB) is a
mountain railway in
Switzerland and is the steepest
cog railway in the world, with a maximum gradient of 48%. The line runs from
Alpnachstad, on
Lake Lucerne, to a terminus near the summit of
Mount Pilatus at an altitude of
2132 m (6994ft). At Alpnachstad, the Pilatus Railway connects with steamers on Lake Lucerne and with trains on the
Brünigbahn line of
Zentralbahn.
The line is
4.6 km (2.9 mi) long, climbs a vertical distance of
1629 m (5344ft), and has a
rail gauge of . The line was opened using steam traction in
1889. The maximum gradient of 48% meant that none of the then available rack designs were up to the job, and the line's engineer,
Eduard Locher, developed a rack design specifically for this line. In the
Locher system, the
cog wheels on the train are mounted on
vertical axles and their teeth engage with gear teeth cut in the sides, rather than the top, of the rack rail. Because of this system, there are no conventional points or
switches on the line, only rotary switches (see photograph) and
traversers.
The line was electrified in
1937, using an overhead electric supply of 1550 V
volts
dc.
