Steam locomotive and tender, No 1275, Class 1001 long boiler, 0-6-0, built for North Eastern Railway, designed by William Booch who developed Stephenson’s original ‘long boiler’ design, built at Dubs & Co. Glasgow in 1874, withdrawn in 1923. Length over buffers: 48' 6"; weight: 35 tons; driving wheels 5 feet, 6 inches.

The North Eastern Railway 1001 Class was a class of steam locomotives designed by William Bouch.

The 1001 Class had a long boiler and were developed along the lines of the long-boiler locomotives which had been patented by Robert Stephenson in 1842. The long-boiler locomotive placed the firebox behind the rear driving axles, which in turn created a longer boiler barrel, increasing the surface area. The long-boiler was considered as a way for the Stephenson standard gauge locomotives to match the power of broad gauge locomotives.

Bouch had been an apprentice to Robert Stephenson & Company and progressed the long-boiler design to create the 1001 Class of steam locomotive, of which 192 were built from 1852. Bouch’s design was first used on the Stockton & Darlington Railway, and after the S&DR was amalgamated into the North Eastern Railway in 1863 the locomotives continued to be built, with the last being delivered in 1875. They were removed from traffic completely by 1923.
