Reyrolle's No.2

In Hebburn library, browsing through the book "Arcs, Sparks & Engineers - A Centenary History of A.Reyrolle & Co.Ltd (1901- 2001)", I came across the photo below:

TR's Armstrong Whitworth D22 of 1933 in original guise as Reyrolle No.2
seen in 1937 outside Hebburn short-circuit testing station No.2

One of the next photos in the book shows an explosion as new switch gear is tested to short-circuit destruction!   

Like Andrew Leslie's shipyard (which started in the mid19th century), Reyrolle's complex was a major  industrial employer in Hebburn.   Reyrolle rode the turn of the century surge on Tyneside in electrical design, development, production, use & export.   Business was good, enabling the company to invest in employee development, help to improve housing, & set up welfare facilities such as large sports fields & parks.
