The Harrington Hump is a modular solution designed to raise short sections of railway platform to reduce the vertical and horizontal gap between trains and the platform edge. It provides a pragmatic, lower-cost alternative to rebuilding an entire platform, aimed mainly at improving accessibility for passengers with reduced mobility, passengers with luggage and wheelchair users.
Design and components
The system typically uses prefabricated modules that are installed on top of an existing platform surface. Modules are shaped to form a ramped approach and level boarding area with tactile edging and slip-resistant surfacing. Key characteristics include lightweight but robust construction, simple mechanical fixing to the platform, and compatibility with drainage and track-side clearances.
- Prefabricated ramp and level modules
- Tactile paving and anti-slip finishes
- Fixings that minimise disruption to the underlying structure
- Modularity allowing tailored lengths and positions
History and development
The name derives from Harrington railway station, where the first production version was installed. Since that initial project, the concept has been adopted at other stations in the United Kingdom. The approach grew out of a need for cost-effective, rapid interventions that improve boarding without the time, expense and planning required for full platform reconstruction.
Uses and impact
Harrington Humps are used where localized height differences prevent level or near-level boarding. They can help stations meet accessibility goals by decreasing the boarding gap and providing a gradual ramp. Installation usually takes significantly less time than rebuilding a platform, allowing quicker delivery of benefits to passengers.
- Targeted accessibility improvements at low-traffic or rural stations
- Interim solution pending larger station upgrades
- Reduced disruption during installation compared with full reconstruction
Limitations and considerations
While effective for many situations, Harrington Humps are not a universal solution. They raise only limited lengths of platform and must be engineered to respect train clearance profiles and safety regulations. Long-term accessibility goals or stations with major structural issues may still require full platform replacement. Operators and engineers assess suitability on a case-by-case basis before installation.
Overall, the Harrington Hump represents a practical, widely used tool in rail accessibility planning: a modular compromise between temporary measures and costly, full-scale platform renewal.
