Data from F C Coleman, "'Kitson Meyer' Locomotives, Colombian National Railways", Railway Review , No 1 (3 January 1920), p. 31.
This sextet were superheated variants of the basic FC de Colombia two-truck Kitson-Meyer type articulated locomotives described in Locobase 3621. They were rated to haul a train load of 100 tons at 16 kph (10 mph) up a 1 in 23 gradient (4.35%) with curves of 80 metres radius. "[I]n actual practice they have proved their ability to perform this service," Coleman reported.
Data from Lionel Wiener (1930). See also "Colombian National Railway", The Locomotive , Vol XVI, No 209 (15 January 1910), p. 13.
Virtually identical to Kitson-Meyer locomotives delivered to Anglo-Chilean Nitrate in the same year (Locobase 3620), these were used on the 3' gauge. Like those, this quartet sported Belpaire fireboxes.
Wiener gave the following tonnage ratings for this class on this railroad:
level grade 2,750 tons
1% 719 tons
2% 392 tons
4% 185 tons
