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