According to the economic theory behind congestion pricing, the objective of this policy is to use the price mechanism to cover the social cost of an activity where users otherwise do not pay for the negative externalities they create (such as driving in a congested area during peak demand). By setting a price on an over-consumed product, congestion pricing encourages the redistribution of the demand in space or in time, leading to more efficient outcomes. (Full article...)

The Glacier Express from Zermatt to St. Moritz (or Davos Platz [Summer only]) in Switzerland is one of the great train journeys in the world. It is not an "express" in the sense of being a high-speed train (it isn't) but rather in the sense that it provides a one-seat ride from end to end, even though the train travels over several different railroad lines; reputedly it is the slowest "express" in the world. The trip on the Glacier Express is a 7½ hour railway journey across 291 bridges, through 91 tunnels and across the Oberalp Pass at 2,033 metres in altitude. The entire line is metre gauge, and large portions of it use a rack-and-pinion system both for ascending steep grades and to control the descent of the train on the back side of those grades.
