Last call for TT:120 JNA box wagons!

The deadline for preorders of our TT:120 MMA/JNA-T ‘EALNOS’ box wagon is fast approaching at the end of June 2026. Development of our first TT:120 wagon has been completed and we’re ready to start production. As a result preorders will close on 30 June 2026 so that production can begin with models expected towards the end of 2026.

There are around 1200 of these wagons on the network now and they are used by nearly every freight operator. These wagons are the ideal accompaniment to the Hornby Class 66 in DB, GBRf and Colas liveries, though they can also be seen hauled by Classes 56, 59 and 60. More information on the real wagons can be found here (including sample consists and route flows).

Models can be preordered from our shop or from any of our retailers with an MSRP of £44.95.

Standard releases

MMA-A DB Red

DB was the first operator to introduce the wagons, with 166 coming into service from 2016. The DB versions feature 9-ribs with bodyside doors and body-mounted parking brakewheels.

DB uses its wagons primarily for traffic from the Derbyshire quarries at Peak Forest to destinations in the Midlands and north of England, along with north Wales.

JNA-T Ermewa, Tarmac grey

These versions are similar to the DB MMA wagons, but do not feature the bodyside doors on each side. They are used primarily to transport stone from Tarmac’s large quarry at Mountsorrel to destinations across the south and east of England.

Version shown has Tarmac branding (versions 102D/E), also available without Tarmac branding (versions 102A/B/C)

JNA-T GBRf blue

GBRf operates several variants of the JNA wagons; the models offered by Revolution represent those used from wagon lessors VTG and Ermewa and have 11 ribs, side doors and bogie mounted brakewheels.

The GBRf wagons are used in a variety of flows.

Version shown has Ermewa branding (versions 103D/E), also available without Ermewa branding (versions 103A/B/C)

JNA-T VTG Mendip Rail silver

Since 2016 Mendip Rail has used a fleet of more than 60 JNA-Ts leased from VTG; they are simnilar to the 11-rib versions operated by GBRf but lack the side doors.

Their main use is for stone traffic from the giant Somerset quarries to depots across the south of England and into the midlands for unloading points that do not have the discharge equipment needed for the company’s large fleet of hopper wagons.

JNA-T Wascosa Network Rail yellow

Network Rail has a fleet of 50 wagons leased from Wascosa in their distinctive yellow livery. They feature the same 11-rib body as the Mendip Rail versions, but have brake equipment closer to that on the original DB MMA wagons with body-mounted parking brake wheels.

They are mainly used to deliver ballast to the network of virtual quarries where it is kept until needed for infrastructure upgrades.

Exclusive releases (all produced in limited numbers)

TMC

TMC have commissioned two exclusive liveries – Touax maroon and Cappagh/VTG blue with 4 numbers of each livery.

Touax

The Touax JNAs are used as part of the Mendip fleet transporting aggregates out of the Somerset quarries across the South of England.

Cappagh

Cappagh / VTG run sets of lighter blue JNAs across a variety of sites in the South of England and also hire out the wagons if needed to other operators (eg a rake of these JNAs ran on the Cumbrian coast for a period). The Cappagh JNAs are a mixture of branded (versions 107A/B/C) and unbranded (version 107D) as per the real wagons. As this is a new commission we won’t have time to prepare livery samples before production.

TTC Diecast / Malc’s Models

TTC Diecast and Malc’s Models have jointly commissioned two DB red MMAs with “Special Products” branding – these were used for different grades of aggregate (but are now back in the general DB pool).

TTC Diecast

TTC Diecast have also commissioned exclusive numbers of some of the “standard” release liveries (as above images) to give customers even more choice as follows:

DB red MMA

TT-EAL-101F      81 70 5500 077-9 

TT-EAL-101G     81 70 5500 122-3

TT-EAL-101H     81 70 5500 399-7

GBRf blue JNA

TT-EAL-103F      81 70 5500 473-0

TT-EAL-103G     81 70 5500 500-0

TT-EAL-103H     81 70 5500 543-0 (Ermewa branded as well as GBRf)

Wascosa/NR yellow JNA

TT-EAL-105F      81 70 5932 159-3

TT-EAL-105G     81 70 5932 167-6

TT-EAL-105H     81 70 5932 179-1

Revolution progresses TT120 MMA/JNA box wagon

Revolution Trains can unveil CAD diagrams of its forthcoming MMA/JNA-T ‘Ealnos’ box wagons in TT120.

MMA-A CAD image

In total Revolution is offering five variants of this commonplace and widely used wagon, and are based on our popular models of the same prototype in OO and N. They can be pre-ordered from Revolution direct or your preferred retailer in DB red, Ermewa grey (with or without Tarmac branding), GBRf blue, VTG Mendip Rail silver and Wascosa/Network Rail yellow.

MMA-A DB Red

DB was the first operator to introduce the wagons, with 166 coming into service from 2016. The DB versions feature 9-ribs with bodyside doors and body-mounted parking brakewheels.

DB uses its wagons primarily for traffic from the Derbyshire quarries at Peak Forest to destinations in the Midlands and north of England, along with north Wales.

JNA-T Ermewa, Tarmac grey

These versions are similar to the DB MMA wagons, but do not feature the bodyside doors on each side. They are used primarily to transport stone from Tarmac’s large quarry at Mountsorrel to destinations across the south and east of England.

JNA-T GBRf blue

GBRf operates several variants of the JNA wagons; the models offered by Revolution represent those used from wagon lessors VTG and Ermewa and have 11 ribs, side doors and bogie mounted brakewheels.

The GBRf wagons are used in a variety of flows; many are currently dedicated to HS2 traffic.

JNA-T VTG Mendip Rail silver

Since 2016 Mendip Rail has used a fleet of more than 60 JNA-Ts leased from VTG; they are simnilar to the 11-rib versions operated by GBRf but lack the side doors.

Their main use is for stone traffic from the giant Somerset quarries to depots across the south of England and into the midlands for unloading points that do not have the discharge equipment needed for the company’s large fleet of hopper wagons.

JNA-T Wascosa Network Rail yellow

Network Rail has a fleet of 50 wagons leased from Wascosa in their distinctive yellow livery. They feature the same 11-rib body as the Mendip Rail versions, but have brake equipment closer to that on the original DB MMA wagons with body-mounted parking brake wheels.

They are mainly used to deliver ballast to the network of virtual quarries where it is kept until needed for infrastructure upgrades.

As can be seen from the CAD diagrams shown, the models feature prototypical detail variations and we are tooling the various different bodies to ensure accuracy. Similarly, there are prototypical differences to the underframes, with numerous separately fitted detail parts, and the models will be supplied with moulded representations of the stone loads, as are our N gauge versions.

The bogies incorproate separately fitted brake pads in line with the wheel treads and load weight indicators, and the couplers are compatible with Hornby models and in standard in NEM pockets.

The real wagons operate across the network, and there are now more than a thousand in service.

As can be seen from the images here and elsewhere online they are the ideal wagon to go with the new Hornby TT:120 Class 66 locomotive.

The models can be ordered direct from Revolution or from your preferred retailer, and production is expected to be complete by Q2 next year.

A Revolution in TT:120

Revolution Trains is offering the MMA/JNA-T ‘Ealnos’ box wagon as our first models in TT:120 – the UK’s newest scale.

There are around 1200 of these wagons on the network now and they are used by nearly every freight operator. As TT:120 starts to grow these wagons are the ideal accompaniment to the first ‘modern’ mainline diesel loco being offered – the Hornby Class 66 in DB, GBRf and Colas liveries, though they can also be seen hauled by Classes 56, 59 and 60.

The MMA/JNA wagons are sturdy and reliable and are used for stone, sand, spoil and ballast. Because they don’t need costly top-loading or gravity-discharge handling facilities – just a siding and a wheel loader – they are very flexible and ideal for short term contracts. This also means they are easy to introduce on your model railway!

TT:120 is an exciting new scale which, for the first time, offers modellers in Britain the opportunity to purchase ready-to-run models with the correct combination of scale and gauge. OO 1:76.2 scale models on 16.5mm gauge tracks are nearly 15% too narrow, while even in N there is an error factor of approximately 7% between scale and gauge.

The Revolution TT:120 box wagons will conform to existing TT:120 standards in wheels and couplers and will work on all main brands of 12mm track including Peco.

We are offering the models in DB, Ermewa, GBRf, VTG-Mendip Rail and Wascosa/Network Rail with five different running numbers for each.

As with our well-regarded models in OO and N the wagons will feature prototypical variations in detailing including 9-rib and 11-rib bodyshells, with or without side cleaning doors, with body or bogie mounted brake wheels and incorporating variations in the positioning and configuration of underfloor brake equipment.

The real wagons are seen across the network, and are used by nearly all freight operators.

  • Please note: The Wascosa versions have been omitted as in engineers’ service they are in widely varied use across the network.

We intend for the MMA/JNA to be just the start of our range in TT:120 and if it’s a success we will look to other models in our range that would benefit the new scale, including other wagons and powered models.

CAD design is underway and will be unveiled shortly.  We anticipate these models to be completed by Q2 2025 and the MSRP is £44.95 per wagon. You can pre-order and reserve your models direct from Revolution Trains or from your preferred Revolution stockist.

All the wagons can be pre-ordered now from our online shop.
