Transport-Consult Karlsruhe GmbH (TTK) was founded in August 1996 by the two main shareholders Planung Transport und Verkehr AG (PTV AG) and Albtal-Verkehrs-Gesellschaft mbH (AVG).

The aim was to create an independent company offering planning and consulting services for the market segment ‘rail-bound public transport’ by combining PTV's experience in the consultancy and software businesses and AVG's operator know-how, especially in the area of tracksharing between light and heavy rail.

With a workforce of around 30 people, TTK has established itself on the European market. Projects in France have been carried out right at the start and the positive development of the French market led to the foundation of a Lyon office in 2002.

The TTK sees itself as a German-French company. Around 50% of the revenue is generated in Germany, 40% in France. The remaining share is attributed to different countries with UK ranking first.
