Abstract [en]

Division of Operation and Maintenance is involved in two work packages in the European 7:th framework research project Sustrail.WP4: Sustainable track and WP5: Business case.Over all SUSTRAIL project aim: SUSTRAIL aims to contribute to the rail freight system to allow it to regain position and market and the proposed solution is based on a combined improvement in both freight vehicle and track components in a holistic approach aimed at achieving a higher reliability and increased performance of the rail freight system as a whole and profitability for all the stakeholders. The SUSTRAIL integrated approach is based on innovations in rolling stock and freight vehicles (with a targeted increased in speed and axle-load) combined with innovations in the track components (for higher reliability and reduced maintenance), whose benefits to freight and passenger users (since mixed routes are considered) are quantified through the development of an appropriate business case with estimation of cost savings on a life cycle basis.WP4: Sustainable trackThis work package will facilitate the need for the railway infrastructure to accommodate more traffic whilst atthe same time reducing deterioration of track and wheels through increasing the resistance of the track to theloads imposed on it by vehicles. This will assist in sustainable achievement of increased speed and capacityfor freight traffic, thus contributing towards making rail freight more competitive. There is a very strong couplingto WP3 since it is essential to undertake a systems approach to analyse the combined track and vehicle loadsand deterioration. The outputs from the WP will also inform the decision making for WP5 that will select the most promising infrastructure technologies for testing and demonstration. The work package is divided into 5 subtasks. Task 4.1: Performance based design principles for resilient trackTask 4.2: Supportive ballast and substrateTask 4.3: Optimised track systems and geometryTask 4.4: Switches and crossingsTask 4.5: Track based monitoring and limits for imposed loadsWP5: Business CaseThis work package considers the business case and implementation issues associated with the vehicle andtrack options developed in WP3 and WP4 respectively. The work package will act as both an iterative filter for the options developed in WP3 and WP4 in order to help focus the engineering development to those options which are likely to have greatest overall net benefits, as well as providing a final business case appraisal for the preferred option. The assessment will include quantifying the Life Cycle Cost (LCC) of each option and a Reliability, Availability, Maintenance and Safety (RAMS) analysis where the parameters for this analysis are informed by the Duty Requirements established in WP2. The work package is divided into 5 subtasks. Task 5.1: LCC and RAMS analysisTask 5.2: User and environmental benefit modellingTask 5.3: Access charges for equitable redistribution of whole system savingsTask 5.4: Technical implementation and phasing issuesTask 5.5: Synthesis of Business Case
