The company is a subsidiary of Keolis, the largest private sector French transport group.
[1] The Lille Metro is a VAL system (véhicule automatique léger = light automated vehicle), which opened on May 16, 1983, the first automatic metro line in the world.
[2][3][4] While most urban lines in Lille were abandoned after 1950, the Mongy remained in service as the backbone of the public transport network of the TCC, the predecessor of Ilévia.
Whilst the expansion of the Metro initially threatened the trams, they were kept in service.
[2][3][4] Ilévia also operates 68 urban bus routes, eight of which run into Belgium.
