Bachmann 31-635A

Tooling

Introduction & Historical Context

The Bachmann GWR Class 64xx 0-6-0PT was introduced in 2015 as a completely new tooling, designed to accurately represent the Collett-designed 64xx class of pannier tanks. These locomotives were built between 1932 and 1937 at Swindon Works, specifically for push-pull (auto-train) passenger services on GWR branch lines. A total of 40 were produced, and three survive in preservation today. The 64xx class was distinct from the more numerous 57xx and 8750 classes, with differences in dimensions, cab design, and operational equipment.

Reviews & Commentary

The model was well received upon release, with Hornby Magazine and Key Model World praising its accuracy and detailing. Reviewers noted that the tooling was entirely new and not a rehash of previous pannier tank models. The cab detailing, separately fitted parts, and smooth running performance were highlighted as standout features. Videos and reviews showcased the model running on test tracks, particularly the BR-liveried 6417.

Social media and forums note its appeal to GWR and BR modellers, especially those recreating branch line and auto-train operations. The model is often praised for its suitability on compact layouts and its smooth, quiet running.

Interesting Notes

• The tooling reflects the earlier body style (6400–6429) with curved cabside-bunker joins and overhanging cab roof lips.
• Designed to represent auto-fitted locomotives with screw reverse and ATC equipment.
• Footplate-mounted lubricators and front tank support variations are accurately depicted.

Operator & Livery

The Great Western Railway (1835-1947) was Britain's most innovative railway company, engineered by Isambard Kingdom Brunel with his revolutionary 7ft ¼in broad gauge system. Known affectionately as "God's Wonderful Railway" and the "Holiday Line," the GWR connected London Paddington with the West Country, Wales, and Birmingham through 3,800 miles of superbly engineered routes.

Renowned for its Brunswick green locomotives, chocolate and cream carriages, and engineering excellence centred at Swindon Works, the GWR pioneered advanced steam technology under chief mechanical engineers Daniel Gooch, George Jackson Churchward, and Charles Collett. The company's legendary locomotive classes—including Castle, King, Hall, and Manor—established performance standards that influenced British locomotive design for decades.

The only "Big Four" railway to retain its original identity through the 1921 grouping, the GWR maintained its distinctive corporate culture until nationalisation in 1947. Today, the company's engineering legacy lives on through extensive preservation efforts, heritage railways, and detailed model railway recreations that celebrate the finest traditions of British steam railway operation.
