FC Central Norte Argentino 2-10-2 Locomotives in Argentina


Class Details by Steve Llanso of Sweat House Media

Class E2/E3 (Locobase 3723)

Data provided by Carlos Alberto Fernandez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000), supplemented by DeGolyer, Vol 72, pp. 234+ and Vol 78, pp. 292+.

The specifications come from a 1926 Baldwin batch of nineteen locomotives that followed Henschel's initial ten of 1921-1922. Later batches of E4 and E5 Santa Fes are shown in the E4 entry, but Fernandez contends that the 61 locomotives are essentially identical.

These were big engines for the gauge and the 27 kg/metre (54 lb/yard) track. They contended with 2 1/2% grades and curve radii of 125 metres (410 feet) or 14 degrees as well as operating altitudes as high as 4,100 metres (13,451 m) above sea level A Belpaire firebox burned the coal and 10" (254 mm) piston valves admitted the steam to the cylinders.


Class E4/E5 (Locobase 3724)

Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000).

Although Fernandez contends that the 1937 Henschels and the 1949 Skodas are essentially identical to the 30 E3s delivered in the 1920s, the later engines have significantly shorter firetubes and larger-diameter cylinders.
