Straddle-monorail is a kind of rail transit system, featured with vehicles with rubber tires running on a precast concrete track beam. With exclusive right of way, sleek trains wrap around the monorail beam with average operating speed of 30-45km/h. Maximum operating speed reaches 80km/h, which is comparable to that of metro, light rails and other urban rail transit modes.

Main features: 1. Good adaptability to terrain, gradeability is up to 100‰, and the minimum curve radius is merely 46m. 2. Excellent environmental adaptability, adopting electric traction with zero exhaust emission; Bright view with small beam width, narrow support column and less land occupation; Great view of the scenery without overhead lines; Environmentally-friendly with less noise and little vibration. 3. Simple construction and short construction period; 4. Good investment and the cost is much lower than that of metro.





APM, a type of urban rail transit system, is featured by unmanned and electric rubber-tyred vehicles operating automatically on special tracks with precast beams and guide rails. With exclusive right of way, APM system is able to operate fast without interference from other means of transport or pedestrians. It is suitable for narrow space with minimum 22-meter turning radius. Gradient is up to 10%.

System integration: system integration refers to the integration of separate equipment, functions and information into interconnected, unified and coordinated systems through structured integrated wiring system and network technology, so as to fully share resources and achieve centralized, efficient and convenient management.

Scope of system integration:

The general contractor is responsible for the integration of subsystems within the work scope of the project, including:

• Vehicle

• Signaling


• O&M and OC


• Track (switch, bumper, running surface, etc.)

• Power rail

• Core method equipment at depot
