fortil Mobility awarded a railway signalling engineering framework contract with RATP
In 2025 fortil Mobility has been appointed engineering manager on a framework contract with RATP’s Signalling and Railway Telecommunications division. The contract runs for three years, with two optional extensions, on a lump-sum, results-based basis. A significant milestone that cements fortil Mobility’s position as a go-to partner in French urban rail.
Supporting the modernisation of the Paris rail network
RATP is significantly scaling up its capital investment in signalling. Two major programmes are driving this growth: NExTEO and the broader asset renewal of the RER and Métro networks. To support this ambition, RATP’s Signalling and Railway Telecommunications division has engaged fortil Mobility to deliver engineering management services. Teams are fully embedded within RATP’s own premises, ensuring operational responsiveness and direct coordination with client teams.
