Reorganisation of the S-bane for driverless operation - Reorganisation of the S-bane for driverless operation
Overview
Background & policy context:
The study has its current actuality due to a number of circumstances related to the S-bane and its environment that makes it particular relevant to assess UTO mode in details now:
New signalling system on the S-bane
The new signalling system, currently being implemented, is the foundation for the future operation of the S-bane. Its functionalities support the transition from manual operation to STO, thereby permitting higher frequency and automation of a number of tasks (e.g. starting and stopping) at the same time. The implementation of the new signalling system is the enabler for further development, an upgrade rather than a new system, from STO to UTO, and without massive associated transformation required.
Procurement of 5th generation of S-trains
The current S-train fleet (4th generation) which were put into operation from 1996 to 2006, will reach the end of their lifetime from 2026 to 2036. Procurement of a new 5th generation S-train fleet thereby needs to take place around this period. The in-any-case procurement of new trains then opens up an opportunity to purchase rolling stock which from the beginning are designed to operate in UTO mode.
Growth in the greater Copenhagen Area
The greater Copenhagen Area has experienced a significant population growth during the last decades. This development – which is considered to continue – impacts the transportation system and creates new requirements to existing infrastructure. The S-bane will experience a higher demand, especially during the peak hours.
Previously promising results
Earlier investigation of the potential for UTO on the S-Bane has shown promising results. A Parsons report from 2010 documents a feasible transfer to UTO, including different operational solutions bringing a stronger financial result. Equally, a 2013 screening report from the Ministry of Transport, Building and Housing state a potential.
Objectives:
The purpose of the investigation has been to explore the possibilities and perspectives of reorganising the S-bane to automatic and driverless operation (metro operation) in connection with the purchase of the next generation of S-trains.
The current S-trains lifespan expires in the years 2026-2036.
Methodology:
An assessment of the possibilities for introduction of UTO on the S-bane requires investigations into a wide range of operational, technical and organisational focus areas. The areas are to a wide extent mutually interdependent and the result from one focus area serve, might have an impact in the investigations in other areas. For that reason, the study has been divided into distinct focus areas making cross analysis more transparent. The areas are:
1) Best performing operational scenarios
2) Feasible and high potential technical solutions related to infrastructure and rolling stock
3) Analysis of associated organisational impact
4) Total financial and social economic assessment
The investigation of operational scenarios has been designed in order to develop a number of potential alternatives making determination of the best performing as clear and significant as possible. Through an iterative process, preferred scenarios have been defined and selected for further investigations based upon relevant key parameters covering operational and financial indicators.
