I was in London the other day and found this: Can anyone explain what the LFB are doing with a bus? The picture I found on Google images by the way - It drove by too quickly for me to photograph it.
It is a command unit. Like a mobile office. https://www.london-fire.gov.uk/abou...ilities/vehicles-and-equipment/command-units/
Spot on and I wonder if there are other models besides the Optare Solo here in the US we called them NABI 30 lfn as command unit vehicles.
The hospital i work at has a 'mobile theatre'. Its a massive truck and trailer with an operating theatre built into. Full lights and sirens too.
