I was describing a while ago.

There was no level ground at the Kaltbad station; the railbed was as
steep as a roof; I was curious to see how the stop was going to be
managed. But it was very simple; the train came sliding down, and when
it reached the right spot it just stopped--that was all there was "to
it"--stopped on the steep incline, and when the exchange of passengers
and baggage had been made, it moved off and went sliding down again. The
train can be stopped anywhere, at a moment's notice.

There was one curious effect, which I need not take the trouble to
describe--because I can scissor a description of it out of the railway
company's advertising pamphlet, and save my ink:

"On the whole tour, particularly at the Descent, we undergo an optical
illusion which often seems to be incredible. All the shrubs, fir trees,
stables, houses, etc., seem to be bent in a slanting direction, as by an
immense pressure of air. They are all standing awry, so much awry that
the chalets and cottages of the peasants seem to be tumbling down. It
is the consequence of the steep inclination of the line. Those who
are seated in the carriage do not observe that they are going down a
declivity of twenty to twenty-five degrees (their seats being adapted
to this course of proceeding and being bent down at their backs). They
mistake their carriage and its horizontal lines for a proper measure of
the normal plain, and therefore all the objects outside which really
are in a horizontal position must show a disproportion of twenty to
twenty-five degrees declivity, in regard to the mountain."

By the time one reaches Kaltbad, he has acquired confidence in the
railway, and he now ceases to try to ease the locomotive by holding
back. Thenceforth he smokes his pipe in serenity, and gazes out upon the
magnificent picture below and about him with unfettered enjoyment. There
is nothing to interrupt the view or the breeze; it is like inspecting
the world on the wing. However--to be exact--there is one place where
the serenity lapses for a while; this is while one is crossing the
Schnurrtobel Bridge, a frail structure which swings its gossamer frame
down through the dizzy air, over a gorge, like a vagrant spider-strand.

One has no difficulty in remembering his sins while the train is
creeping down this bridge; and he repents of them, too; though he sees,
when he gets to Vitznau, that he need not have done it, the bridge was
perfectly safe.
