Overhaul - Midlife train

Description

The Copenhagen Metro M1+M2 has been in operation for 18 years and is know for high service availability and customer satisfaction. The demand for public transportation in Copenhagen continues to increase while the Metro's rolling stock and infrastructure is aging. The current fleet of 34 metro trains have a life expectancy of 25 years. The system has now however, reached a point, where it is going from being a new system to becoming a incumbent system, where replacements and renewals have to be done more frequently and the scale and complexity of the activities are increasing. Metroselskabet is therefore undertaking this mid-life overhaul to ensure the Metro continues to deliver a high service availability and customer satisfaction while increasing capacity at the same time. The scope of this work is to extend the life expectancy of the fleet in order to deliver high service availability going into 2035. Hence investments in life-extention of the fleet is required. Lot 1: The objective is to extend the operational life of the fleet of 34 vehicles on the M1/M2 line at Metroselskabet so they can continue in operation until 2035. The first two vehicles of the overhaul process are considered as a pre-series production with a longer lead time in terms of allowing a more detailed verification of the scope with the opportunity for altering the scope. The extended time will also allow a longer time for carrying out the overhaul on the first two vehicles. For the systems where an updated design due to obsolescence is to be prepared for the overhaul, the evaluation and final determination of the solutions will take place on the first vehicle. The execution of the overhaul must ensure that all systems covered by the overhaul will be in the same state on the entire fleet of vehicles. Throughout the entire overhaul process, the work shall be verified by inspections and tests as stated in the tender documents. A First Article Inspection shall be carried out on the first vehicle in the pre-series production as a release for the continuation of the overhaul. Transportation and other related tasks are included in the tasks.
