8~1/6；
2nd, engineering construction is fast：It is quick to build construction is simple, whole system construction period half a year~mono- year or so；
3rd, dismountable moving：As urban development changes, other places can be transferred to from convenient disassemble of existing line；
4th, ride comfort is unobscured：The big glass compartment of hommization, passenger enjoy advanced comfortable experience by bus；
5th, quickness and high efficiency facilitates：Above crowded urban express way, empty iron is with 50-80 kilometers/hour or so of speed
Spend noiseless pass through；
6th, any weather is adapted to：Empty iron wheel is run in closed orbit, from bad weather or the shadow of underground ponding
It rings；
7th, floor space is minimum：Empty iron construction floor space is small, figuratively, it is only necessary to which the light pole on road side is added
Slightly, you can prop entire empty iron；
8th, special geology is adapted to：Underground spring, hard rock stratum are awaited a subway the applicable empty iron in the city that can not be constructed.
Empty iron is also known as hanging type aerial monorail transit.In empty iron system, when car body commutates, to use to track switch.Track switch is
A kind of line connection equipment that rolling stock is made to be transferred to another station track from a station track.The turnout rail of empty iron mainly by switch track and
The two straight tracks parallel to each other connected by switch track form, and switch track includes two commutation tracks to cross one another, commutation
The end of track respectively respectively with a straight orbit connection, is changed in order to be located at the car body on a straight track by one
