Public transport buses and coaches Tarn

This urban transport network offers 11 bus lines that criss-cross the whole of Castres town centre, from the station to the Borde Basse leisure centre, and even as far as Mazamet. A Libellus Chrono service that crosses the city in record time is also available. This network is also a good example of the city's and the agglomeration's desire to continue the transition to electric vehicles. The municipal services are equipped with a number of models and Libellus is following suit. A new hybrid phase is currently being put on line.

Occitanie's intermodal lines, from their little name "Lio", are grouped together within the Occitanie region's public transport network. Inaugurated in September 2018, replacing the existing departmental networks, it also integrates the TER Occitanie network. In total, Lio comprises hundreds of regular coach lines, over twenty TER lines, transport-on-demand services in six départements, as well as several hundred school lines. Stops include Albi, Castres, Gaillac, Carmaux, Lacaune...
