Ambulances are generally considered emergency vehicles authorized to be equipped with emergency lights and sirens. Generally, vehicles count as an ambulance if they can transport patients. However, it varies by jurisdiction as to whether a non-emergency patient transport vehicle (also called an ambulette) is counted as an ambulance. These vehicles are not usually (although there are exceptions) equipped with life-support equipment, and are usually crewed by staff with fewer qualifications than the crew of emergency ambulances. Conversely, EMS agencies may also have nontransporting EMS vehicles that cannot transport patients. (Full article...)

The Glacier Express from Zermatt to St. Moritz (or Davos Platz [Summer only]) in Switzerland is one of the great train journeys in the world. It is not an "express" in the sense of being a high-speed train (it isn't) but rather in the sense that it provides a one-seat ride from end to end, even though the train travels over several different railroad lines; reputedly it is the slowest "express" in the world. The trip on the Glacier Express is a 7½ hour railway journey across 291 bridges, through 91 tunnels and across the Oberalp Pass at 2,033 metres in altitude. The entire line is metre gauge, and large portions of it use a rack-and-pinion system both for ascending steep grades and to control the descent of the train on the back side of those grades.
