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 ClassâŻ56âŻ077 Original Railfreight Livery Diesel Locomotive is a 4âŻmm (OO) scale model released as part of the âRails of Sheffieldâ limited edition. The locomotive is numbered 56077, built to represent the prototype that carried original Railfreight livery between 1986 and 1990, and it is fitted with interior lighting. It carries a 21âpin DCC interface (DCCâŻ21) and a 5âpole motor with twin flywheels, geared for prototypical running speeds and providing fine slowâspeed control.
The model is based on original works drawings from Electroputere and BREL and has been completely reâtooled to cover all 135 ClassâŻ56 locomotives built from 1976 to 1984. Key external details include a distinctive fabricated cab shape, cutâaway buffer beam, diamondâmesh side grilles, cantrail and roof grilles, and steel cab and window frames. Internally the chassis is alloy, the bogies are supplied as separate components for improved detail, and photoâetched grilles are fitted throughout.
Electronic features comprise allâwheel pickâup with magnetic Hall sensors to prevent flange squeal, DCC sound based on a custom ESU project, an EM1âtype speaker plus a sugarâcube speaker for balanced low and high frequencies, and roof fans that can be driven by a DCC function output or by DC. Optional EM/P4 wheelset packs and both standard and revised cantrail grill options are available.
The model is intended to meet the same high standard of finish as Cavalexâs PGA and BBA/BLA wagon ranges, offering a high level of detail and innovation for collectors of British Rail ClassâŻ56 locomotives.
