SLNO Railway Station (01-14)

Zephyr monorail car (TBM) pulling into Second Norway's 'Terminal B' Station.

A monorail is a railway in which the track consists of a single rail, typically elevated. The term is also used to describe the beam of the system, or the vehicles travelling on such a beam or track. Most privately operated railway networks in Second Life are monorails, predominantly utilizing automated Zephyr or Mistral monorail systems manufactured by TBM, one of the largest monorail manufacturers in Second Life.


The term originates from joining mono (one) and rail (rail), from as early as 1897,[1] possibly from German engineer Eugen Langen, who called an elevated railway system with wagons suspended the Eugen Langen One-railed Suspension Tramway (Einschieniges Hängebahnsystem Eugen Langen).[2]
