Authority: NETWORK RAIL INFRASTRUCTURE LIMITED (Central government)
What is being bought
Published requirement descriptionPlease 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 & can run in traffic.
- TRM – Twin Jib Track Relaying Machine - Used for the lifting & handling of track panels, in the context of track renewals where panels are to be loaded / unloaded onto a train. 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. Lifting capacity of 12 tonnes, self-propelled only when on the worksite, & is therefore Loco- hauled to & from the job, (cannot run in traffic). Full radius reach of 13metres.
The Contractor would be required to provide Operators and Fitters who are competent to operate items of plant in both normal rail traffic and within possessions.

How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
i
How often small and medium firms win.
Share of awards where the winner’s size is known.
The counts under this question show how many awards have a known supplier size.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
i
How often local firms win similar work.
Winners with a registered address in the delivery region, out of awards with a known address.
Local means the winner is registered in the region where that award was delivered. The market figure counts awards delivered in South East England.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners were registered outside the region where that award was delivered.
i
How long buyers here take to decide after bids close.
Middle value in days from the bid deadline to the award date, on competitions that published both.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards have an award date within 250 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
Both shares are minimums: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?
i
How many bids past lots received.
Each colour is a bid-count range. Only competed lots with a published count are included.
Past bids do not predict this tender.

4–648% / 29%

How did awards compare with estimates?
i
Where winning prices landed against estimates.
Each colour shows awards below, close to or above the published estimate, one lot at a time.
On a framework or DPS, prices are agreed when work is called off.
Past prices are a guide, not a bid price.
Not comparable on a framework or DPS: the price is set later, on each call-off.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
