Revolution Trains is to produce the all-new Class 93 tri-mode locomotive being built for Rail Operations Group by Stadler as its first powered model in 00/4mm scale.
Rail Operations Group has ordered ten of the new Class 93 locomotives, with options on a further 20, and the first is to be delivered in early 2023.
The Class 93 is designed to operate on 25kv overhead power supply, with an inboard diesel engine, or using heavy duty batteries; allowing it to be almost silent while in stations or other built up areas while optmizing efficiency across the network and maximizing low carbon benefits. The Class 93 will be able to run at speeds of up to 110mph and the diesel power unit is specified to be powerful enough for prolonged mainline running, not just ‘last mile’ operation.
Revolution Trains is delighted to have been chosen by ROG and Stadler to produce the Class 93 tri-mode locomotive, which is arguably the most exciting and innovative development on the real railway for many years.
Neil Bennett, Executive Chairman of Rail Operations Group, said: “Along with our well-established rolling-stock movement business, we have very exciting plans for the Class 93 including low-carbon logistics services operating at speeds of up to 110mph. I am delighted to be working with Revolution Trains on reproducing the locomotive in model form.”
This will be Revolution’s first powered model aimed at 00 gauge/4mm scale modellers, but Revolution has already delivered, or is developing, six 00 wagons: TEA tankers, MMA/JNA ‘Ealnos’ box wagons, IZA Cargowaggon twins (a Kernow exclusive), IWA ‘Sfins2’ vans, IWA ‘Rfnoos’ timber carriers and FWA ‘Ecofret’ container flats.
The model will be to 4mm:1ft scale, 1:76.2 with RP25-110 wheels with space for EM/P4 fitting. They will feature our usual high levels of detailing including photo-etched and separate parts where appropriate, prototypical lighting arrangements, 21-pin DCC socket, and heavy metal chassis with full provision for DCC Sound. DCC Sound-fitted models will also be available.
We will offer multiple numbers, factory-fitted buffer-beam details at one end (though a spare NEM coupler will also be included for customers who wish to couple the loco at both ends) and we will investigate the provision of a DCC operated pantograph mechanism.
The full specicifation is subject to revision during the design phase, but will be confirmed by the time we open the order book.
Rail Operations Group has exciting plans for the Class 93, and while initially they are likely to be used mainly to service ROG’s existing and well-established rolling stock movement business, the company also sees the locomotives being used as part of its proposed ‘Orion’ high speed centre-to-centre low carbon logistics trains as well as 110mph intermodal services. For more information see here.
ROG is planning to begin trials of its first converted Class 319 units in April 2021. The images below show the first unit being unveiled last month.


The Class 93 models will be offered in ROG’s stylish green and black launch livery, and it is understood that they are to be named after Roman Gods.
The terms of the licence – which covers both 00 and N gauge models – mean that ROG and Stadler will work closely with Revolution, sharing important technical specifications, 3D data and design drawings, to ensure the models are as accurate as possible and that any changes made during construction are incorporated.
Class 93 Initial Specification
- Heavy diecast chassis with smooth electric motor and flywheels and provision for DCC and Sound
- 4mm-ft/1:76.2 scale 00 (16.5mm) gauge, with provision for simple conversion to EM/P4
- Separately applied etched metal or fine plastic details
- NEM coupler sockets with fully detailed, factory-fitted bufferbeam at one end (second coupler in accessory pack)
- DCC provision: 21 pin decoder socket
- Prototypical lighting arrangements, switchable for DC users where necessary
- Twin speakers on sound-fitted models
- RP25 (110) wheels with provision for simple conversion to EM/P4
- We will investigate options for a DCC operated pantograph mechanism, though the pantograph itself will be cosmetic
It is intended that the models will be delivered as soon as possbile after the prototypes enter service.
