96TS Jubilee Underframe Modification Project- Drawgear

Tender description

<p>The Jubilee line Underframe Modifications Project (JUMP) is currently undertaking an option definition/feasibility exercise to correct structural and drawgear issues on the Jubilee line fleet. This questionnaire is the start of the project&rsquo;s early market engagement to inform the options and understand the market capability and capacity to deliver a solution. At the feasibility stage JUMP assumes that a contract will be awarded to a single supplier that will include the following works: &bull; Modify or replace the drawgear release elements across the entire Jubilee line fleet (except for DM Autocoupler positions). Options include, but are not limited to: o Redesign of current mechanism o Replacement of drawgear with alternative design &bull; To demonstrate that the proposed solution works in a collision scenario and does not fail in normal operations &bull; To demonstrate adequate proof and fatigue load requirements will be met through appropriate calculation at the design stage &bull; Production of prototype units for testing and analysis &bull; Static and dynamic testing of proposed solution to provide evidence that proof and fatigue load requirements have been met &bull; Manufacture of production units to replace entire fleet (except for DM Autocoupler positions) &bull; Replace coupler support bracket and inner longitudes across the entire fleet</p> Keywords: Rolling Stock, Drawgear, Modification, Tube Stock, Fatigue Load, Prototype
