Why were monorails popular?

Advantages. The primary advantage of monorails over conventional rail systems is that they require minimal space, both horizontally and vertically. Monorail vehicles are wider than the beam, and monorail systems are commonly elevated, requiring only a minimal footprint for support pillars.

The primary advantage of monorails is due to the smaller size of a beam compared to rails. This may translate to cost reduction due to less material needed for support pillars. Also, compared to elevated trains, the beam blocks less sky and may be less aesthetically displeasing.

Perhaps the most notable is the 2009 Monorail crash that killed young driver, 21-year-old Austin Wuennenberg.

The entire set of the beam, the bogies, the wheels, etc. is more complex and expensive for a monorail. Monorail requires a lot of stuff around the beam, often made of expensive rare metals, with a lot more maintenance. Monorail beam itself must be built and maintained to high specifications.

Yes. There are 42 urban monorail systems operating in the world today. Each day they safely shuttle millions of passengers between hundreds of stations with 99.5% reliability -- the highest reliability of any transit mode.

Monorails have seen continuing use in niche shuttle markets and amusement parks. Modern mass transit monorail systems use developments of the ALWEG beam and tire approach, with only two suspended types in large use. Monorail configurations have also been adopted by maglev trains.

Driverless operation Innovia Monorails are all fully automated and use a variety of train control technologies. However, the Riyadh and São Paulo monorails are both equipped with CITYFLO 650 communications-based train control.

Monorails are safe Whether they are of the straddle-beam or suspended variety, modern monorail technology makes derailment virtually impossible.

MORE DETAILS

Monorail is, by design, a grade-separated system. They do not interfere with existing transport modes. Unlike conventional rail systems, straddle monorails wrap around their track and are thus not physically capable of derailing, unless the track itself suffers a catastrophic failure.

MORE DETAILS

Modern monorails rely on a solid beam as the running surface and are divided into two classes: straddle-beam and suspended monorails. Straddle-beam monorails are more common, with trains straddling a steel or reinforced concrete beam. Suspended monorails, like the Wuppertal Schwebebahn in Germany, are less common.
