Our team

TTK employs around 30 international staff members having at their disposal extensive experience in all fields of public transport. As a result of the collaboration between French and German professionals within project teams, clients benefit from the experiences acquired in the neighbouring countries. The know-how transfer between France and Germany, and increasingly also with other countries, is a trade mark of TTK. It is further complemented by international experience gained in a large variety of projects, some also in the research sector.
