TfL Infrastructure

Working within a highly regulated and time constrained environment, SES l has developed a reputation for safe timely delivery of challenging tasks.. TfL and its Framework Contractors have utilised our pool of rail and civil engineering experienced staff to augment output on the London Underground Infrastructure. 

SES 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 resources, focused on delivering the work safely and within the time constraints imposed on TfL’s network. Working directly with TfL’s Maintenance Division we provide and operate a fleet of 7.5T Tipper Lorries to provide logistic support services to the track maintenance gangs.

Working closely with TfL’s Transplant Division we provide experienced and skilled staff to maintain and operate their specialist plant such as the DISAB VAC, VCM and Weed Killer trains.

In conjunction with our Special Projects Division, we provide specialised engineering support to London Underground and we have aided delivery of major projects such as the Baker Street to Bond Street tunnel relining and various acid and water ingress prevention schemes.
