Abstract
The Dutch railway system is equipped with a 1500 V DC system. In order to
facilitate further growth, the 1500 V system has needed and will need significant
investments in substations. In 2001 the railway sector analysed the system and
decided to continue with the system until at least 2017 and to re-evaluate the
system performance again a decade later. 25 kV AC was considered the best
option but difficult to realised in a \“brownfield situation” on existing tracks.
ProRail started a quick-scan study in 2011 and 2012 in which the actual
existing options for power supply as described in European standards
(TSI Energy) were put to the test. It led to new insights, which were not available
back in 2001, and related to updated traffic development insights and a new
possibility and importance of sustainable power consumption. A migration path
to an alternative traction system was subsequently elaborated in 2013, the
so-called 3 kV DC alternative, which was developed jointly with a societal
business case. It was found that the current 1500 V DC system can still be
improved in terms of efficiency but that a 3 kV alternative can achieve a step
change in energy savings as well as travel time savings. The draft business case
and migration plan will be the start for discussions with the operators and
development of a joint business case and recommendation of the railway sector.
The process has not been finished but key results from the analysis and lessons
learned from this process will be discussed in this paper.
Keywords: railway traction, energy savings, travel time savings, sustainability.
