Abstract

The demands of railway infrastructure development are increased to meet rail transport requirements, particularly, for those large scale equipment and oversized cargoes that are often beyond railway gauges such as vehicle/infrastructure structure gauges. Railway administrators have to check clearances between out-of-gauge trains carrying with these railway out-of-gauge freights (ROFs) and all of railway infrastructures along their routes, i.e., bridges, tunnels, platforms, signal equipment and over-head power lines to ensure its safety. Therefore, the safety of ROF transportation requirements should be taken into consideration in railway infrastructure development and maintenance projects. This paper presents methods for modelling of ROF loading outline and the minimum infrastructure structure gauges. A railway gauges doublechecking algorithm has also been developed to calculate gap distances between vehicles and infrastructures which can provide useful information for railway designers, engineers and managers in the design, construction and maintenance of railway infrastructures. A case example of ROF transport routing problem is used to demonstrate the clearance safety requirements. The results show that gap distances between vehicles and infrastructures are major factors that can impact on ROF transportation safety, which should be integrated into the design, construction and maintenance projects of railway infrastructures.
