Value proposition

Merling advisors can introduce parties to experience, know-how and best practices on transportation planning, infrastructure, rolling stock & contract management. Read more...
When a public transport authority, operator or infrastructure manager moves to a new area or encounters problems with the existing rail system this calls for the best know how, experience and practices.

Merling adds value for its clients by offering assessments, evaluations and second opinions of:

  • Transportation planning: from strategic planning to timetable design
  • Infrastructure development: specifications, tender documents, bid evaluation, design
  • Rolling stock: fleet planning, procurement, maintenance
  • Contract management: contract design, target setting, performance management
New challenges could be the introduction of light rail or high speed rail, new rolling stock, power systems or signalling systems, but also organisational aspects like the introduction of competition on rail or in contracting.


Merling work with the best experts, well known with the Dutch Railsystems & operations and able to provide practical solutions for other railsystems.
