Les TMR projettent d’aménager un atelier de maintenance et de mise en service de matériel roulant ferroviaire dans ces halles. En particulier pour Catogne III, la création d’un nouveau bâtiment administratif indépendant avec au rez un atelier et un magasin communiquant avec la halle bogies existante ainsi que la création de bureaux, une salle de conférence, des sanitaires et des vestiaires pour les personnes travaillant sur le site.
