Data from "New Goods Engines for the Highland Ry," The Locomotive Magazine, Vol V (March 1900), p.42. Works numbers 3842-3847 (1900), 4240-4243 (1902). Dubs then became part of North British and the 1907 class had works numbers 17896-17897.
Like the "Small Ben" 4-4-0s profiled in Locobase 8917, these locomotives, designed by Peter Drummond, had inside cylinders. They were based on the Small Bens and produced by the same Glasgow builder. They had double-bogie tenders with a significant capacity.
Four received cross-water-tube fireboxes comprising 246 sq ft of direct heating surface that apparently were satisfactory, but not retrofitted to any of the others.
The dozen Barneys accompanied the Highland in its absorption by the LMS in 1923 and given a 3F class rating.. The first was scrapped in 1936 and only 7 were nationalized in 1948. These were all retired by 1952.
Data from "'Six-Coupled Tank Engines, Highland Ry," The Locomotive Magazine, Vol X (15 February 1904), p. 22; and "The Highland Railway and Its Locomotives", Locomotive Magazine, Volume XXV [25] (15 March 1919), p. 37. Produced at Inverness in October and December 1903 and in May 1904.
As the author of the LM report observes, this trio represented a "somewhat strange but nevertheless very pleasing mixture of the designs of Mr. Jones, the past, and Mr P Drummond, the present locomotive superintendent."
Jones had rebuilt some 1863-vintage singles (originally produced by Neilson) with new boilers pressed to a higher degree in 1896 (two came new from Sharp, Stewart, one from Lochgorm) but the resulting increase in thrust cracked the frames behind the cylinders. Meanwhile, the Highland was scrapping some Class N Sharp, Stewart four-coupled goods from the same year. Combining the wheels, connecting rods, and some of the inside motion of the Ns and the boilers from the failed conversion resulted in a strong, if relatively light set of tank engines. (Boiler detail note: in addition to the 1 3/4" tubes shown in the specs, the boiler had 3 1 1/2" tubes.) A photo shows a substantial-looking locomotive whose drivers bulk larger than usual in a shunting engine.
At the time of the 1904 report, 22 was a switcher at Inverness while 23 was pulling goods trains on the Perth-Pitlochry section. All three joined the London, Midland & Scottish (LMS) in power classification 2F. As part of a rationalization, the trio was scrapped in 1930-1934.
