Taltal Kitson-Meyer Locomotives in Chile

Class Details by Steve Llanso of Sweat House Media

Class 51 (Locobase 3622)

Data from Wiener (1930). Works numbers were 4432-4434 in 1906; 4504-4506 and 4512-4514 in 1907.

Virtually identical to Kitson-Meyer locomotives delivered to Anglo-Chilean Nitrate and the Colombian National railway. All were very satisfactory in the mountainous terrain and tight curves of these mineral roads.

Taltal's main line was 169 miles long and presented grades of up to 4.8% as it climbed from 39 ft above sea level at Taltal on the coast to 9,216 ft ASL at Bianca-Estella just 83.3 miles away. The locomotives also rode on very light rail (originally 41 lb per yard, later upgraded to 56.5 lb per yard).
