a complete train, an LED lamp etc.). structure heavily depends on the system under study and in many cases, it is difficult to define a standard cost structure for LCC breakdown analysis. We propose to examine the project of the conversion of the regional rail Fraisses-Firminy-St-Etienne line into a tram-train corridor. As a result of effective RAMS strategy and management, quality, safety, and sustainability become an integral factor of the entire railway system rather than being limited to just the development phase. the RAMS standard. In this thesis, risk management have been investigated in a case study which helped to realize how the construction industry works with this concept. Our results show that, in ordinary conditions, the optimal scenarios are those that minimise the planned headway. 2014 ARS, India: Bangalore Blue-S7 Begins at 11:35 AM, Thursday, November 13 Current Time: 11:32 AM RAMS Management for a Complex Railway System: A Case Study Numerous operational scenarios were explored by analysing different planned headway and rolling stock configurations. Graffica’s HERMES team was asked to model two UK networks with a variety of scenarios running from the present day until 2043. ; until the Final mission, where all sub stations in the city are supervised. The study relates to the rail project ‘HSL-Zuid’ which is delivered on the basis of a DBFM (Design, Build, Finance and Maintain) contract. For the complex systems used in the railway industry, the basic methods of reliability, availability, and maintainability (RAM) analysis, and the subsequent decision making as illustrated in the previous chapter may not be suf cient.
