\nWith the aim of electrification of the railway system, the power supply for 39km of railway lines is required.
\nThe subsystem chosen for the life cycle analysis is the pole from the overhead catenary system, which can be seen in the picture below as a support mast.
\n\"railway-system-energy-supply\"<\/a><\/p>\n

The poles withstand all forces acting on them and transmit them to the foundation. These can be the weight of the catenary, the tensile forces with which the catenaries retightened, but also the wind forces,\u00a0 aerodynamic loads acting on catenary, and supporting equipment.
\nThe picture below shows the pole structural design:<\/p>\n

Geometry and materials<\/span>
\nIn this case the pole is a conical spun made of concrete, which is well suited for high-speed lines due to their high load-bearing capacity. Spun concrete is reinforced with pre-stressed steel (longitudinal and spiral).\u00a0 They have a circular cross-section and a cavity in the center that extends from top to bottom.<\/p>\n

For one spun concrete mast the following materials are used:

Maintenance interventions<\/span><\/p>\n

The lifetime of the system is defined as 60 years. Due to its inherent characteristics there is almost no need for maintenance over the life time, in major cases replacement is more suitable.\u00a0 The pole structure and foundation is inspected every 24 month. Maintenance repairs, such as small cracks in the concrete, are fixed every ten years.<\/p>\n

1. Inspections
\nDescription: Regular preventive visual inspection of pole structure and foundation
\nIntervals: every 1 year
\nDuration: 2 days<\/p>\n

2. Repairs in the foundation
\nDescription: Repair of cracks
\nIntervals: every 10 years
\nDuration: 10 days<\/p>\n

3. Repairs in pole structure
\nDescription: Repair of cracks
\nIntervals: every 10 years
\nDuration: 5 days<\/p>\n

Project Information System (PRINS in German) for the Federal Transport Infrastructure Plan 2030<\/h2>\n

To improve the port connection of Brunsb\u00fcttel, electrification of the Wilster – Brunsb\u00fcttel rail line from Wilster to a new transfer station to be built between DB Netz AG and ChemCoast Park Brunsb\u00fcttel in the area of the former Landscheide station is planned. The supplementary electrification of the Marschbahn in the Itzehoe – Wilster section will allow freight trains to\/from Brunsb\u00fcttel to be continuously electrified without reloading in Itzehoe.<\/p>\n
