This procurement, currently in the planning stage and scheduled as a tender process, aims to enhance railway maintenance capabilities across various regions in the United Kingdom, specifically UKI, UKK, UKJ4, and UKJ2. As part of the procurement timeline, a market engagement survey has been published, inviting insights from potential suppliers, with submissions closing on 30th April 2026. The procurement is set to proceed within a framework agreement with services to commence in April 2027 and conclude in March 2035. This tender represents a significant opportunity for businesses specialising in railway maintenance and related services, particularly those capable of providing skilled operators and fitters for heavy rail machinery. Suppliers in the sectors of railway maintenance vehicles and track maintenance services, with experience in utilities and above-the-threshold procurements, stand well-placed to compete. Companies that can deliver innovative, efficient machinery solutions compatible with existing rail infrastructure and offer comprehensive support services are encouraged to engage with the process, contributing to the growth and optimisation of the UK's railway system. ## Notice Please note that this is a market engagement exercise to assist us in gaining insight into the supply and operation of RMMM within the UK market Machine Definitions RMMs are classified as: a) large - 5.5 tonne gross laden weight and above. b) medium - less than 5.5 tonne gross laden weight and greater than 1 tonne. c) small - 1 tonne gross laden weight and less. The classification of RMMMs into three bands is concerned mainly with their ability to assist each other in the event of failure. The three classifications have no influence on the application of this standard - the acceptance criteria for all RMMMs are the same, irrespective of size. * TRAMM - General Purpose Track Maintenance Machine - Used for the carriage of equipment & materials to & from depot / worksite. Is fitted with a medium duty, medium reach crane arm. Able to carry short lengths of rail, with a payload capacity of approx. 8 - 10 tonnes. Is able to thimble Continuously welded rail (CWR). Is self-propelled & can run in traffic. * High Capacity TRAMM (HCT) - Specialist Track Maintenance Machine - Used for the carriage of equipment, materials, and up to 40 lengths of 60ft rails, to & from depot / worksite. Is fitted with a medium duty, long reach crane arm. Hi-Capacity TRAMM cannot thimble CWR.

Is self-propelled only when on the worksite, is therefore Loco hauled to & from the job, (cannot run in traffic). Lifting capacity of approx. 11 tonnes, but at a fixed length, limited radius / reach. * GPC - General Purpose 12t Crane - Used for general-purpose lifting operations within context of all types of track work.
