Tram is a transportation system optimized for tourist spots, smart cities and large shopping malls, and it is a new transportation system with convenient movement within the tourist spots, shopping complex and last mile movement.
Mono + rail. A generic term for a single gauge or a railroad with only one rail. A single-track railway is not a monorail.
The advantage of monorail is that the construction cost is very low, and it can be easily installed even in cramped and complicated sections.
In particular, the construction cost is exceptionally low, and if it is designed as a suspended monorail, the construction cost per km can be reduced by about 25% compared to urban maglev trains. Even over-seated monorails can be shaved off by about 10% compared to urban maglev trains.
If we consider the construction cost per km of suspended monorail, it will be reduced by almost 75% compared to heavy trains. Even if you dig underground, the construction cost of the monorail is about 50% cheaper than that of heavy trains based on the construction cost per km.
Due to the nature of the monorail, it does not have a deck (except for the branch), and the area required for its construction is comparatively less than that of other light railways, so it is less aesthetically pleasing and, above all, the construction cost is cheaper.
