Rather than prescribing solutions, we instead look to the market for creative, resourceful and novel approaches to problem solving to create new value for TfL by doing things better, quicker or cheaper. Transport for London (TfL) relies on adhesion management to maintain a safe, reliable, and high-frequency railway system while preserving asset health. Both high and low friction levels at the wheel-rail interface can cause safety issues like delays, derailments, and asset damage. To address these, TfL uses various operational, procedural, and technical solutions. During autumnal months, outdoor sections of the network (55% of the London Underground) face low adhesion due to fallen leaves mixing with iron oxides on rails. This can lead to delays, cancellations, wheel flats, and even collisions or derailments. TfL's current solutions include vegetation management, rail adhesion trains, Traction Gel Applicators, seasonal timetables, and reduced brake rates. Any new solution must consider the diverse infrastructure of TfL's network, which includes a mix of above-ground and underground stations with varying platform dimensions and designs. The network also features different rolling stock and signalling systems, some automated and others manually driven. Service intervals range from 22 to 36 trains per hour. Any proposed solution should ensure safety across these varied conditions without compromising service frequency or asset longevity. Problem statement: How might we target railhead contamination such that we retain optimal (or as near as feasible) levels of friction on the railhead; allowing us to run a high-frequency service year-round regardless of the weather? ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** planned - **CPV codes:** 34600000, 34900000, 60000000 - **Delivery regions:** UK - **Description:** TfL wishes to engage the market to seek feedback on emerging approaches and solutions for rail adhesion management.
