Cavalex Models have announced a newly-tooled Class 56 in 4mm.
The model is already significantly advanced and currently at the tooling stage, having been in the works for the past few years. All variants of the 56 are being tooled, to accurately cover all 135 locomotives produced between 1976 and 1984.
The Cavalex 56 has been designed completely from scratch, based on original works drawings from both Electroputere and BREL. Having incorporated numerous innovations into the model which they plan to showcase in the future. Whilst the 56 has been released by other manufacturers in the past, it was an obvious choice for Cavalex given the prototype ran with all of the released and forthcoming wagons, and being 56 fans, Cavalex wanted to capture the distinct differences between the four main versions of the âGridâ. They have deliberately chosen prototypes that donât conflict with existing models of the class, whilst also releasing liveries never seen in 4mm scale. This extends to liveries not seen on certain versions; for example Red Stripe Railfreight on a Romanian built Class 56.
The locomotive will incorporate the following features:
- A wealth of separately fitted parts, including bogies which arenât just one piece mouldings to allow for proper detail relief
- Photo etched grilles throughout the model
- All wheel pick up and innovative automatic flange squeal activated via magnetic hall sensors
- Alloy chassis to allow the locomotive to pull prototypical wagon rakes
- 5 pole motor with twin flywheels, geared for prototypical running speeds with superb slow speed control
- 21 pin DCC interface, with easy DCC fitting provision via removable roof panel to the number 2 end
- DCC sound with custom ESU project for our factory fitted sound version and stay alive fitted to all models
- Sound model has an EM1 type Speaker with additional sugar cube speaker in the chassis as standard for a balanced combination of low and high frequency sounds to accurately reproduce the prototype via a custom recorded sound project
- Drop in EM/P4 wheelset packs available to order separately to coincide with the release of the model ORDER HERE
- Separately motor operated roof fans via a function output on DCC, or when moving on DC
- Etched name plates as appropriate
- Both standard and revised cantrail grill options depending on prototype.
The Cavalex 56 will be produced to the same high standard of finish as the highly regarded PGA and BBA/BLA wagons, incorporating similar levels of detail and innovation.

Cavalex Models Class 56 055 Loadhaul Diesel Locomotive is a limitedâedition 4âŻmm scale model released under the âRails of Sheffieldâ theme. It carries DCC 21 compatibility, includes interior lighting and bears the manufacturer part number CMâ56055âLH. The model represents the initial privatisation era of British railways and is numbered 56055, built in Doncaster and listed as postâ1995.
Key physical details include rubberâsealed cab front windows, steel cab side windows, diamondâmesh side and cantrail grilles, and revised roof grilles above the electrical compartment. The cabâs partial bufferâbeam cowling and removed side plates reflect the prototypeâs appearance. The locomotive is reproduced from original Electroputere and BREL working drawings, covering the four main versions of the Class 56 built between 1976 and 1984.
Technical specifications feature a fiveâpole motor with twin flywheels geared for prototypical running speeds, an alloy chassis suitable for pulling wagon rakes, and a 21âpin DCC interface with removable roof panel for easy fitting. Sound is provided by an ESUâbased system with an EM1 speaker and a sugarâcube speaker in the chassis, offering balanced low and high frequencies. Additional options include dropâin EM/P4 wheelset packs, motorâoperated roof fans controllable via DCC or DC, and interchangeable cantrail grill variants.
The model incorporates numerous separately fitted parts such as detailed bogies, photoâetched grilles and etched nameplates, and uses allâwheel pickup with magnetic hall sensors to prevent flange squeal. Cavalex aims to match the high finish standards of its PGA and BBA/BLA wagon ranges, delivering a highly detailed and innovative representation of the Class 56 locomotive.
