TfL Infrastructure

SES has diversified into rail projects beneath the TfL umbrella. Working within a highly regulated and time constrained environment, SES Rail has developed a reputation for safe timely delivery of challenging tasks providing skills already held within SES. TfL and its framework contractors have utilised our rich pool of rail and civil engineering experience to augment output on the London Underground infrastructure. 

SES Rail are a primary supplier to TfL, assisting them to consistently deliver their engineering hours and possession maintenance works. SES are acknowledged as a company that delivers and supplies high quality well trained resource, focused on delivering the work safely and within the time constraints imposed by the tube network. SES Rail possess a wide range of LU core skills within our teams which include PWTEH trained staff through to electricians and other rail and civil engineering skills. 

In conjunction with our sister company Special Projects, we enrich the projects run by TfL. Through specialised engineering support to London Underground we have aided delivery of the Baker Street to Bond Street tunnel relining and acid ingress prevention schemes. SES Rail also supports Transplant in resourcing and maintaining their fleet of DISAB and RSDT trains.
