Data from P C Dewhurst, "Locomotive Practice of the Chilian Transandine [sic]", Locomotive Magazine, Volume 20 (15 June 1914), pp. 161-169 (data on p. 169). See also Ian Thomson, "The Transandine Railway: a Hundred Year Long Financial Disaster that Still Attracts Investors", pp. 1-8, archived at [], last accessed 21 October 2017. Works numbers were 3477 in 1908 and 3623 in 1911.
Locobase 20297 shows the six Kitson-Meyer rack & adhesion locomotives that wound up supplying most of the steam power on the Chilean Transandine. This pair presented an alternative power setup and a bigger boiler and grate. The lead six-driver bogie used a large 21.25" (540 mm) x 17.72" (450 mm) rack engine to turn no fewer than three rack pinions. Under the rear boiler, firebox, and bunker was the four-axle adhesion-traction unit.
Certainly they were powerful, but one of them soon derailed at a point on the line where it landed "in a spot from which it could not be economically recovered."
