It is the first acquisition since Keltbray Infrastructure Services was sold by its parent company to private equity firm EMK Capital in August.
Linbrooke’s rail business is an approved Network Rail tier-one Principal Contractor, delivering end-to-end ‘design and build’ signalling, telecommunications and associated power solutions across the UK Rail infrastructure since 2003.
The move secures the long-term future of the £54m-turnover Linbrooke rail business including 140 employees.
KISL Chief Executive Officer, Darren James said: “We are pleased with this ‘on strategy’ acquisition of the Linbrooke rail business, generating additional capability to further penetrate the UK’s decarbonised transport market.
“I look forward to working with my new colleagues as we build an exciting and rewarding future.”
