Effective January 2023, Dr Andreas Kaldenbach became head of Railway Strategy and Consulting and a member of the Executive Board of NEXTRAIL GmbH. Dr Kaldenbach has proven himself to be a genuine railway enthusiast in management positions at Deutsche Bahn AG and has made a career as an expert dealing with challenging operational, technical and procedural issues in the railway sector.


For instance, before joining NEXTRAIL, he was responsible for qualifications in rail operations and infrastructure maintenance for the DB Group in a management position at Deutsche Bahn AG. In previous years, Dr Kaldenbach worked for DB Netz AG in the field of digital interlocking technology. As digital interlocking technology progressed, he was responsible for the strategic roll-out development on a national and international level as well as for supporting the so-called reference implementations and pre-series projects of DB Netz AG. The focus was on both technological and economic evaluations of the existing technology in order to be able to draw conclusions for a roll-out. The first series of projects were also anchored in corporate planning.


After studying physics and business administration, Dr Kaldenbach earned his doctorate in solid-state physics at RWTH Aachen University. His quick and successful entry into the railway sector, which would shape his future, was achieved through his work in the areas of strategy development and technology and innovation management at the top consulting firm Radermacher & Partner GmbH, Munich.

A shortage of skilled workers and long training processes presented enormous challenges for personnel management in the area of control-command and signalling system. As part of the project, the status quo was assessed, and efficient ways of improving and simplifying personnel management were developed and effectively implemented.

With the aim of integrating the regional area more strongly into corporate topics, a new company programme was drawn up by order of the DB Netz AG management board and was successfully anchored in the organisational units of the headquarters and regional divisions.

With the advent of the new digital interlocking technology and the associated stronger linking of control-command and signalling system and telecommunications, it became necessary to fundamentally revise the vision of the maintenance professions in signalling, telecommunications and energy supply. Hidden potential in maintenance also had to be leveraged over the long term by bundling the aforementioned functions.

As the development of digital interlocking progressed, it became necessary to develop and implement a roll-out strategy. The focus was on technological and financial evaluations of the existing technology in order to be able to draw meaningful conclusions for the roll-out. The first series of projects were also anchored in corporate planning.

Assumption of interim management for preliminary and development planning with the main task being to support and launch the first digital interlocking series projects in the preliminary planning phase.

Taking over project management to migrate specific qualifications from service providers to an operating area. In particular, the task was to oversee the transformation of the affected organisational units and to be responsible for change management.
