Picture of a North Eastern Marine Doxford engine on test.
I have a list of 424 Doxford engines built on the Tyne:
Hawthorn Leslie: 132 engines
North Eastern Marine: 113 engines
Richardson & Westgarth: 33 engines, some were Hartlepool built some NEM when they were one and the same.
Swan Hunter (Neptune): 95 engines
Wallsend Slipway: 51 engines.
Additionally Vickers Armstrong Barrow are credited with 26 engines but there is some uncertainty about how many of these were Tyne built and how many were Barrow built.
These were only Doxford engines but Sulzer, Werkspoor, Gotaverken and turbines were also built in large numbers. A reminder of thousands of unassuming people whose work has never been appreciated by the public, but who worked with accuracy and skill day in, day out and not only on the Tyne, but throughout the country.
Since posting this, I've been through Tony Wickens list and Joe Clarks tables and found that Hawthorns completed 147 Doxford engine contracts, nine of which were twin engine installations so Hawthorn Leslie built 156 Doxford engines in total as well as being partners in the Seahorse project.
