Class 50s – from Accurascale

23 November 2022
With delivery expected late 2023, and tooling "almost complete" six locomotive identities are revealed, with exclusives to follow.

Accurascale has made public its plans to manufacture 1:76 scale / 4mm:1ft scale models of the English Electric Class 50. The models are to be the third and final member of its English Electric (EE) six-axle trio that began with the Class 55 in 2018 and the Class 37 in 2019.

Tooling is almost complete but due to a local COVID shutdown in China the first sample has been delayed for the 2022 Warley show. This first sample will follow early in the new year.

Six locomotives make up the first announcement, with some Accurascale Exclusives to follow soon. Prices range from £189.99 for the DC/DCC ready examples to £299.99 for the DCC 'Accurathras' sound-fitted models. Delivery is expected late Q4 2023.

The Accurascale Class 50 model began with a 3D laser scan of 50017 at the Great Central Railway in 2019. Building on its growing range of diesel and electric locomotives, the EE Type 4 features its most impressive specification yet, with its twin-speaker set up, working radiator fan, flange squeal sensor, and full lighting package that includes preservation-era oddballs, engine room and cab lighting with auto off feature, and eight cab configurations with illuminated driver’s control desk.

The Class 50 Alliance also allowed Accurascale to visit its fleet based at Kidderminster Diesel Depot on the Severn Valley Railway on several occasions, even raising 50044 on jacks to allow the Accurascale research team unprecedented access to the underframe. The "full gamut of changes" experienced by this class has been included on its extensive tooling suite to create "the definitive Class 50", including optional multiple-working equipment, missing handrails on D400, original headcode or plated with marker lights or sealed beam lights, no headlight, blanked headlight and headlight, wind deflectors, sandbox fillers, ‘grilled’ windows on refurbished locomotives (including the first pair which retained the window grommit for several years), early or late cast bogies, dynamic brakes, roof scavenger port, NRN or GSM-R radio equipment/fittings, seven- or 12-blade radiator fan and roof walkways.
