Why all these industrial's, surely ex BR locos are more interesting?
The BR shunter fleet was largely a product of the 1950s modernisation plan, and in most examples was basically a "proven" industrial design with BR's specific requirements added, i.e. code light assemblies, vacuum train braking, driver's cookers, etc. The biggest exception is the Class 08-11 groups, which stem from the LMS experiments of the 1930s and were built in volume after the war because it was already proven (if not already out-of-date!). Production of 08s ceased c.1960, notably much the same time as the launch of the Sentinel (in 1959/60) which advanced industrial locomotives well away from their BR predecessors. (Sentinel locos were trialled with BR but no more shunters were being bought and no orders resulted).
Look at it this way...
|BR Class||Type||Industrial origin|
|01||Barclay 0-4-0DM||Standard Barclay model similar to locos built during WW2 for WD|
|02||Yorkshire 0-4-0DH||Standard YEC design, but using pneumatic clutch rather than the manual clutch offered on the industrial version|
|03||0-6-0DM||Class 03 based on class 04|
|04||Drewry 0-6-0DM||Drewry design similar to locos built during WW2 in 0-4-0 and 0-6-0 layouts.|
|05||Hunslet 0-6-0DM||Standard Hunslet design (an earlier 0-4-0DM version too)|
|06||Barclay 0-4-0DM||Same comments as Class 01|
|07||Ruston 0-6-0DE||Based directly on Ruston "LSSE" class but notable change of higher cab roof (many industrial designs anticipated low bridges)|
|97s||Ruston 0-6-0DE||Ruston 165DE but with manual disconnect in gearbox for towing purposes (PWM650-654)|
|97s||NB 0-4-0DHs||Two versions of NB 0-4-0DH bought by BR, based on standard industrial model. (D2700-D2780)|
|97s||HC 0-6-0DMs||Two versions of Hudswell Clarke 0-6-0DM (SSS gearbox) based on industrial offering (D2500-D2519)|
In most cases there were more examples of the maker's industrial run-of-the-mill version built than their BR equivalent, but as enthusiasts tended to see the latter from days spent at platform ends or bunking into sheds, the locos of industry have remained the "cinderellas" of the loco world. So will Andrew add an 08 to the collection - very unlikely!
