Shunting in the Stuttgart Digital Node (DKS)
Challenges, improvements and potential for shunting operations with ETCS
The introduction of the European Train Control System (ETCS) – particularly in the Level 2 “without signals” configuration – brings with it many opportunities, but also challenges. This applies not only to train movements, which are often the primary focus, but equally to shunting operations. Within the pilot project Stuttgart Digital Node, initial simplifications in shunting operations have already been implemented and further potential has been identified. The insights gained demonstrate how coordinated interaction between technology and operations can enable simpler, more cost-efficient and higher-performing solutions. A technical article outlines how technological advancements and adapted operational concepts can help to future-proof shunting operations under ETCS.
The DKS shows that shunting remains demanding even under ETCS, while at the same time offering significant opportunities for operational simplification. Such developments can help to make operational processes more efficient and stable, thereby strengthening rail operations as a whole in the long term. With enhanced processes and regulatory frameworks, as well as new approaches to the visual authorisation of shunting movements – for example through a so-called “blue light” – a large proportion of the light signals still required today could potentially be eliminated in the future. Additional potential lies in the use of shunting areas, as already implemented in countries such as Denmark and Norway, which could enable more flexible shunting within defined areas without the need for additional light signals.
Furthermore, the new operating mode Supervised Manoeuvre (SM) opens up additional possibilities for shunting operations: in future, shunting movements can also be performed in push mode and under full supervision – provided that the length of the train section ahead of the traction unit is reliably known (e.g. through the Digital Automatic Coupling).
