Vehicles corridor along the flooding Danube in Budapest - Hochwasser - Bus - Trolley - Truck

Different vehicles - Ikarus and Volvo buses, Soviet ZiU 9 and and Hungarian Ikarus-GVM trolleys etc - over the HÉV (S-Bahn) tunnel along the flooding Danube in Budapest. The reason is: the water pressure does not cause damage in the tunnel structure. A Bem rakparton, a HÉV alagút fölé nehéz járműveket állítottak, hogy a víznyomás ne rongálja meg az alagutat.
