Smarter Access, Safer Delivery: The Apsley Easter Blockade

During the Easter blockade at Apsley station, Enable Infrastructure and Enable Design delivered critical Access for All (AfA) foundation upgrades for Network Rail under a collaborative one‑team approach with Taziker. By engineering a bespoke temporary access solution with Cordek Ltd, the team completed deep piling and complex civils works in a constrained station environment with zero On Track Plant (OTP) dependency. The innovative approach reduced risk, improved safety and enabled the site to be handed back ahead of schedule.
