Heavy Heavy Tractor Sound - We Go One Step Beyond With HTG's D6724!

[Warbonnet]

We’ve built close relationships with a number of preservation groups over the years, and they’ve been invaluable in helping us create our models. From giving us access to measure and scan real locomotives, to recording their sounds and experiencing these incredible machines up close—it’s something we never take for granted.

That’s why we always look for ways to work with them whenever we can. Together—with your help—we raise funds to keep these expensive ladies running.

We’re back again with another special Class 37, aiming to raise as much as possible to support the real locomotives we all love. You’ve already seen this with our recent SRPS announcement, and now we’re partnering with our friends at the Heavy Tractor Group once again. This time, we’re recreating 37714 in near-original condition as D6724, finished in 1960s condition BR Green with small yellow panels.

Locomotive History

Built at English Electric’s Vulcan Foundry in August 1961, D6724 was initially allocated to 31B March, before moving to 30A Stratford the following month. It became a dependable member of the depot for five years, working a wide range of duties including passenger services, the Manchester–Harwich ‘boat’ train, parcels, and freight.

By the mid-1960s, now fitted with small yellow warning panels, newer locomotives began displacing Stratford’s fleet. D6724 returned to March in August 1966, before moving between depots for several years. In February 1974, it transferred to Thornaby and was renumbered 37024 under TOPS.

A major collision in 1980 led to plated nose doors at both ends. Aside from a short loan to Cardiff Canton in 1981, it remained a steady Eastern Region locomotive until May 1987, when it moved north to Motherwell and Eastfield.

In October 1988, following refurbishment at BREL Crewe, it re-emerged as 37714 in Railfreight Metals livery, becoming one of the Class 37/7 “Heavyweights”. It was later named Thornaby Depot in September 1992, although the nameplates were removed just five months later.

After further service and overhaul work, it was stored in October 2000, but returned to action in May 2001, heading to Spain to help construct the AVE high-speed network—repained into a distinctive blue livery for its overseas duties.

It returned to the UK in 2011 as one of just six survivors, joining Direct Rail Services. After a short spell in service, it was loaned to the Heavy Tractor Group in 2016, repainted into triple-grey with Metals branding, and today remains a core part of operations at the Great Central Railway.

The Model and the Mission

To reduce the financial and manpower burden on preservation groups, we now produce, fund, and retail these models on their behalf. We handle production costs, sales, packing, and distribution, allowing these groups to focus on maintaining and operating the real locomotives—work that is largely done by volunteers.

Importantly, a portion of every sale goes directly back to these groups, helping to keep our railway heritage alive. You also get a high-quality model in presentation packaging, while the Heavy Tractor Group receives stock to sell at open days and events.
