Not a tram, not a bus and not a trolley bus - but what?

Everyone knows how a tram differs from a bus. And if you somehow combine both modes of transport? No, this is not about a trolleybus, but about a car on rubber wheels moving along a special reinforced concrete chute. Similar lines were developed in Germany by the notorious Mercedes, and are called O-BAHN - “O Bano”. And so that the tires of the vehicle do not rub against the walls of the gutter, protective wheels are provided. When the gutter ends, the car becomes an ordinary bus.


There is also an opposite solution on the Wonderful World channel, but again, this is not a trolleybus. In front of you in the frame is something with a pantograph (like a tram), rubber tires, like a trolleybus, and a central additional wheel. The latter does not allow the vehicle to leave the route and provides the minimum possible distance between oncoming "bass", which is important in a metropolis.

Against this background, double-decker trams from England look like a common occurrence. But Metrotram is definitely not there. But he is in Volgograd. There, trams run part of the route underground. And what about the city's "cogwheel road" and bulletproof carriages? What other bizarre "crossbreeds" of popular public transport exist in the world, you will learn from the video.
