About TSO
TSO is a French construction and civil-works company based in Chelles, in the Île-de-France region. A specialist in railway track construction, renewal and maintenance, plus catenaries.
In railway work, activity must fit into traffic-possession windows, with sector-specific safety rules and approvals. Contracts typically cover track renewal, switches, catenary or formation, delivered in phases so service is not interrupted.
In this sector, approved references and experience of night or weekend working are decisive. A directory should record the exact specialism, because track, catenary and railway civil works are different trades.
