Engineering the future of steam in Yorkshire
Precision engineered by Diamond Engineering (formerly CTL Seal) in Sheffield, we're re-creating a BR Standard Class 6 Steam locomotive using 21st century engineering. Our aim is to re-create the original engine, but make significant improvements to it's overall performance. Our new locomotive will be:
​
> Cleaner & Greener
> More Powerful
> Greater efficiency
Find out how we're achieving this...

2026 Open Day
Saturday 11th April 10am -4pm
​
Come and see the Locomotive in all it's glory at our Locomotive Works, located at Diamond Group (formerly CTL Seal), Butterthwaite Lane, Ecclesfield, Sheffield S35 9WA. Everyone welcome, members and non-members alike. Lots to see and do and we may even have the BBC filming! We'd like to get lots of new members, old and young signed up, so we look forward to seeing you all.

** Latest Project Update**
​
Following on from William Cook donating 6 driving
wheels to the value of £140,000, the next phase of work is underway for the coupled wheels. Roller bearings have been delivered, tyres and axles are on order. Design work on the castings for the roller bearing cannon axleboxes is nearing completion.
The hind covers for the cylinders have been cast and
machined - these feature the support for the front of the slidebars recently installed on 71000 'Duke of Gloucester'. An order has been placed for the casting of the front cylinder covers.

Another Milestone reached - we have Tyres!
A big day for Hengist, 6 tyres for the 6' 2" coupled wheels were delivered, just 16 weeks after the order. Each tyre weighs 656 kg. The tyres are made to British Standard BS 5892 Pt 4, which is for the specification for rolled railway tyres.
They were made by Schmiedewerke Groditz in Germany and were ordered through their Sheffield based agent Railway Wheelset and Brake Ltd.
Axles are next on the list!
Geoff Turner
Engineering Director
1956 - 2026
It is with great sadness that the Standard Steam Locomotive Company have to announce the death of Geoff Turner, our Engineering Director. Geoff passed away on Saturday 28 March 2026. Geoff was a key member of the team that reorganised the company in 2011 and created the foundations for our organisation. Geoff was instrumental in forming the successful relationship between SSLC and CTL Seal/Diamond Group. Geoff will be sorely missed by his family and colleagues.
​
The Hengist Team is proud to recognise the extraordinary contribution of Geoff Turner, whose involvement with the project spans more than 20 years and is driven by a lifelong passion for steam locomotives. As Engineering Director of the Hengist Project, Geoff has played a pivotal role in shaping the technical direction and progress of the build.
​
In a remarkable act of generosity and commitment, Geoff has donated £150,000 to the project. This substantial contribution will fund the completion of the locomotive’s driving wheel set, including the casting of the cannon axle boxes, machining of all associated components and final assembly. This milestone will ultimately enable the Hengist team to assemble a fully rolling chassis by 2027.
​
Geoff has expressed his hope that this donation will inspire others to support the project, demonstrating both the scale of commitment required and the belief that this long-lost BR Standard Class 6 locomotive can be successfully completed in the years ahead.
​
In recognition of his dedication and lasting impact, the Hengist team has unanimously agreed to name the locomotive’s boiler after him—an honour befitting a passionate and devoted railwayman whose contribution will live on through Hengist for generations to come.
