Posted by Oliver Davies on

Accurascale Surprises Nobody With A Nifty Class 50 in 00/4mm! 

Accurascale today announces the Class 50, the third and final member of their iconic English Electric (EE) six-axle trio that began with the Class 55 in 2018 and the Class 37 in 2019. With their award-winning ‘Deltic’ now in customers’ hands and the first of the much anticipated Type 3s due to leave our factory in the coming weeks, it is now time to reveal the full details of the next classic main line locomotive to join their growing roster.

The first run consist of six locomotives, available to pre-order DCC ready for £189.99 and DCC sound fitted for £299.99. All can be pre-ordered with FREE UK Delivery.

The models are expected Q4 2023.

The Model
The Accurascale Class 50 is the culmination of over three years of development that began with a 3D laser scan of No. 50017 at the Great Central Railway in 2019. Building on Accurascale’s growing range of diesel and electric locomotives, the EE Type 4 features their most impressive specification yet, with Accurascale’s ground shaking twin-speaker set up, working radiator fan, flange squeal sensor, 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 graciously allowed Accurascale to visit their fleet based at Kidderminster Diesel Depot on the Severn Valley Railway on several occasions, even raising No. 50044 on jacks to allow the Accurascale research team unprecedented access to the underframe! The full gamut of changes experienced by this class have been included on Accurascale’s 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.
Tooling is almost complete but due to a local COVID shutdown in China the first sample has been delayed in arriving in time for the 2022 Warley show. This first sample will follow early in the new year. Six locomotives make up the first announcement, with delivery is slated for late Q4 2023.

Prototype History
The class developed a huge following towards the end of the 1980s as older locomotives fell by the wayside and the ‘Hoovers’ were lined up to be the next major victim of ‘Sprinterisation’. With just 50 examples built and all – initially – wearing evocative names drawn from Royal Navy warships that were applied from the late 1970s, many enthusiasts developed intense bonds with individual Class 50s that rivalled even the last days of the ‘Deltics’. Although the final withdrawals came in 1994, this passion for the class was happily translated into preservation and 18 examples are still extant with five currently main line registered.
Delivered from Vulcan Foundry, Newton-le-Willows, between September 1967 and December 1968, the new 100mph diesel-electrics were developed from EE’s successful DP2 prototype with the intention of speeding up services north of Crewe to complement the accelerated electric timetable on the southern section of the West Coast Main Line. They were numbered D400-449, later 50001-50050 under TOPS, and were initially allocated to Crewe, albeit leased to British Rail as part of an innovative deal that made their approval much more palatable to government officials.
The 2,700hp locomotives were the first class to be entirely delivered in BR corporate blue and later gained the ‘Hoover’ nickname due to the intense sucking sound created by the twin inertial filters at the No.2 end. The fleet was initially deployed on passenger and parcels services between Crewe and Glasgow, with forays north as far as Inverness, as well as trains to Blackpool, Liverpool and Manchester. Notably they were also fitted with rheostatic braking – already common on electric locos – that was particularly useful on the long down grades from the summits at Beattock and Shap. As the wires began to march north again from 1970, multiple working equipment was installed fleet wide while freight work became a greater part of their remit, their slow speed control kit proving particularly useful for MGR coal operations to Ironbridge and other power stations.
Although EE had hoped to deliver what would have essentially been a fleet of ultra-reliable DP2s in a restyled carbody – courtesy of the Design Panel – BR eventually settled on a substantially revised specification that was packed with electronics and would prove to be the Achilles heel of the class, especially when the
