The cog railway differs from the usual one in that it has another one laid between two smooth rails - a cog railway, which drives the drive wheel of the car. Such roads are made in areas with large slopes.
Since the traditional railroad arrow is not very suitable here, the designers resort to various funny technical perversions.
1. Arrow using brute physical force.
As you can see, the rails are perfectly bent:
2. Transformer arrow
The same manually:
3. The creeping arrow
4. And, finally, the unique Swiss change-over arrow
