Trackwork design on a Mass Rapid Transit (MRT) system is complex with respect to coordination requirements and minimal availability to mitigate construction deviations. The fundamentals of the track geometry and system parameters will provide the operational requirements of the MRT system. Safety and risk assessments will define the facilities to ensure safety requirements are adhered to.
Detailing the trackwork with its associated infrastructure (power rail, point motors, crossovers, cable throughs, trackforms) and rail ancillaries requires detailed considerations of geometric constraints, speed profile, clearance requirements, system interface, constructability and maintainability. BIM modelling has proven it value to identify clashes, missing detailing and constructability issues leading to accurate detailing of the works.
This presentation will outline the key issues and solutions in trackwork design on an MRT system project.
