»In which we go metric but not electric

I took an arduous climb (on a cog-wheel railway, the world's longest and perhaps also steepest) to the summit of Pike's Peak, to the height of 4298 m (or 14,110 ft). This was the highest altitude at which I have stood since taking a similar rail up Jungfrau near Interlaken, in Switzerland.
UPDATE: In fact, Jungfraujoch is only 3454m, but to its credit has an all-electric railway. (The Manitou Springs and Pike's Peak Railway is, curiously, diesel despite being of Swiss manufacture.) Pike's Peak may be the highest terrestrial altitude I have attained.
