A major goal of this project is to develop a unit of train vehicles for accelerated replacement of existing open-steel-plate-girder railway bridges. Through this project, a few sub-goals can be archived:

▪ Increasing a driving speed of trains as well as riding quality and safety.
▪ Accelerated replacing construction with minimum environmental disturbance.
▪ Exploitation of a new market of accelerated replacing construction.

This projects have conducted several researches to archive the main goal:

▪ Analyzing trends of related technologies and patents
▪ Development of superstructure
- Designing optimum superstructures with concrete and steel
- Static and dynamic tests
- FE analyses with various train speeds
- Manufacturing a sample superstructure
▪ Design and manufacturing crane-vehicle
- Design and structural analysis of a crane-vehicle
- Laboratory test of accelerated replacing construction
▪ Development of adjustable bridge bearings in vertical direction
▪ Economic evaluation of the suggested accelerated replacing construction
- Cost analysis of construction
- VE and LCC analysis

The results of this project can be used for:
▪ Replacing of existing open-steel-girder railway bridges
▪ New constructions of short span railway bridges
▪ Adjustable bearings can be used for other fields such as MAGLAB bridges
▪ Providing basic data for expand this project to replacement of long span railway bridges
