Keeling-Lindo bought these two plantation saddle-tankers to support the new 10,000 ton sugar factory at Bernard Lodge, which opened on 14 February 1920. At the time it was the biggest on the island and its construction was due, said the somewhat breathless account, " to the gigantic efforts of Messrs. Lindo Bros, who are know throughout Jamaica and Central America for doing things big."
The factory was served by plantations planted out by the proprietors and contracts with other cane farmers. Connecting all of these was the network of standard-gauge tram lines on which the two "30-tonners" would pull a trailing load of 4-6 cars weighing 30 tons over level ground and around "easy" curves. One sidelight on delivery: The locomotive was to be "packed in boxes weighing not more than 12 tons" presumably because the biggest cargo-handling equipment available would be on the ship that brought them to Jamaica.
