Cordoba & Belmez Beyer-Garratt Locomotives in Spain


Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 20300)

Data from "Steam Tender Locomotive, Cordoba & Belmez Railway, Spain", Locomotive Magazine, Volume 20 (15 September 1914), p. 237. See also "C=rdoba á Espiel y BTlmez (forma parte de la lfnea de C=rdoba a Almorchón)", blog entry dated 24 February 2012 at [link], last accessed 21 October 2017. Works numbers were 1690, 1723-1725.

Archibald Sturrock had first experimented with powered tenders on Britain's Great Northern, where he equipped fifty 0-6-0s with cylinders and valve gear driving the three-axle tenders.

The concept of six powered axles in a short wheelbase attracted the C a B, which had a section of 3% grade that required substantial effort to conquer. The 1914 LM articles claims that the engines must have been successful as ten were produced in Glasgow. But all the Spanish-language sources (including spanishrailway.com) say that only four of the class were ordered and only two of the four were set up with steam tenders.

In addition to the two outside cylinders positioned in their usual forward location, Two more cylinders of smaller dimension (340 mm/13.38" x 500 mm/19.7") installed below the very front of the tender drove the center axle. Although the boiler and firebox undoubtedly served two cylinders adequately when burning high-calorie Welsh coal, however, adding two more dashed expectations as the boiler simply couldn't keep up.
