Manufacturer description

56046 Features:

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 ‘Grid’. They have deliberately chosen prototypes that don’t 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:

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 56 046 Construction Sector Diesel Locomotive is a 4 mm scale model released as a limited‑edition “Rails of Sheffield”. It carries DCC 21 status, interior lighting and is listed as Class 56 with manufacturer part number CM‑56046‑TGC. The model represents the British Rail sectorisation period and is numbered 56046, built to the Doncaster prototype that operated in the construction sector from 1989 to 1993.

Key physical features include rubber‑sealed cab front windows, steel cab side windows, partial buffer‑beam cowling, and diamond‑mesh side, cantrail and roof grilles. The locomotive’s cab side plates are removed to match the prototype.

The model has been newly tooled from original Electroputere and BREL drawings and aims to cover all 135 locomotives built between 1976 and 1984. It incorporates a high level of detail such as separately fitted bogies, photo‑etched grilles, etched nameplates and optional revised cantrail grill.

Technical specifications include an alloy chassis, a five‑pole motor with twin flywheels geared for prototypical speeds, and a 21‑pin DCC interface with a removable roof panel for easy fitting. Wheel pickup uses magnetic Hall sensors to activate automatic flange squeal. DCC sound is provided via an ESU custom project, with an EM1‑type speaker and an additional sugar‑cube speaker for balanced low‑ and high‑frequency reproduction.

Optional features are separate roof fans operable via a DCC function output or DC, and drop‑in EM/P4 wheelset packs available as separate orders. The model is finished to the same high standard as Cavalex’s PGA and BBA/BLA wagons, offering a detailed and innovative representation of the Class 56 locomotive.
