EMPL with manufacturing sites in Austria and Germany exhibited this very interesting M.A.N. tunnel fire-fighting vehicle with dual cabs at Interschutz 2010.
The Gotthard tunnel has a truck with a turntable platform below the chassis, so that it can literally spin 360 degrees once it reaches the fire scene. It also has on board oxygen, both for the crew and to supply air to the engine, as in the famous fire some years ago the oxygen level in the tunnel fell so low that vehicle engines all stalled out. This dual cab is a cheaper solution, but let's hope it never sees action.
