Stockton & Darlington 0-4-0 Locomotives in Great_Britain

Class Dart (Locobase 10240)

Data from "Early Stockton & Darlington Locomotives," Locomotive Magazine, Vol VII (November 1902), pp. 184-185.

The engine is described as having been delivered with 12" x 18" cylinders and a boiler pressed to 60 psi. The specifications refer to the locomotive as it was when displayed at the S & D's 50th-anniversary celebration in 1875. By then it had a tall dome placed well forward, splashers over the upper arc of the wheels, a windscreen with square lights, and a short tender.

Class Huddersfield (Locobase 10255)

Data from "Early Stockton & Darlington Locomotives", The Locomotive Magazine,Vol VIII (10 Jan 1903), p.28.

This was one of Edward Bury's last 4-coupled freight engines and it had the classic spacing between the drivers, hemispherical firebox, and unprotected footplate. The author notes about Bury's designs tha they did well in service "...till higher speeds rendered them too unsteady,whilst the staying of the firebox crown and the shape of the box generally were unsuitable for the greater pressures which gradually came into use."

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class Locomotion (Locobase 637)

The first engine with drivers coupled on the outside by a connecting rod and built-up drivers bound by a tire. Locomotion could draw 90 tons of cars at 6-8 mph. This was also the first engine built by Robert Stephenson and Company, one of the most influential engine builders in steam locomotive history.

It had one 24" diameter flue
