Highland Railway Drummond 0-6-0 Class

From Wikipedia, the free encyclopedia

These locomomotives were introduced in 1900, to the design of Peter Drummond.

They were fairly standard for British practice of the time, inside cylinders with 5 ft diameter driving wheels and a general Drummond family appearance.

The first six had inside bearing double bogie tenders, rather like the watercart designs brother Dugald was supplying on the London and South Western Railway.

Four more (Nos 18 to 21) were supplied by Dübs and Company in 1902. These omitted the watercart tenders but had another Drummond family speciality - cross water tubes in the firebox. No 21 is recorded as retaining this boiler in unmodified form until 1934.

Seven of them survived to fall into the hands of British Railways.
