The oilfields line Construction and opening At the beginning of the 20th century there had been no settlement at all at the coast, though Comodoro Martin Rivadavia had anchored there in 1890 to explore the area. It was the agriculture of Colonia Sarmiento and the area around the lakes which required a small port and warehouses to aid the movement of produce to the north. By1901 the first buildings had been erected and a proposal had been aired for a railway line from Rada Tilly (south of Comodoro Rivadavia) via Colonia Sarmiento to Colonia San Martin. Whilst Arturo Calman had obtained authorisation for this, it was never actually constructed (1). The town also received Africaaner migrants seeking a new start after the 'boer' republics were absorbed into the new Union of South Africa. In 1907 oil was discovered and the growth of the town was assured. A new railway route was surveyed in 1908 and was originally intended to form part of a single network with the other lines. Approval for the first 104km. from the coast was given on June 17 1910, at an anticipated cost of 25,300 gold pesos per km. The first materials reached Comodoro Rivadavia aboard the steamer Mendoza in April 1910 and gangs of Russians, Spaniards, Poles, Bulgarians, and others were set to work, presumably organised by languages for ease of command. Early days at the coast (2). A muelle is under construction and there appear to be piles of materials. Whether the oil drums were brought in to provide fuel, or were early samples of the area's main export, is not clear. This muelle was eventually strongly reinforced and it lasted at least until the building of the new harbour in the late 1920s.
By 1911 the first 112 km to Cañadon Lagarto was in operation. Work reached Colonia Sarmiento by 1914 and was halted there pending the ending of the war and easier economic times. By the 1920s, as explained elsewhere, the plans had been revised and links to the Las Heras line and north-west towards Trevelin were now to be of 75cm. gauge. In the event, not even this was done and the railway ran on in isolation for the next sixty years.
The route
The station building, seen above next to the sea at the foot of the street in front of the camera, is shown in close-up below.
Over the years the station gained a platform canopy and a few extra rooms. The building survived the closure and saw a number of community uses but is now (2001) being restored. The photo below was taken after some of the later additions had just been removed. Note the water tower still surviving at the far end of what was the platform.
From the opposite end, the picture below shows the station in operation.
On the south side of the station yard just west of the main buildings lay the turntable. This was unusual in being of dual gauge, with an inner set of rails for the 75cm gauge Baldwins of the Ministerio de Obras Publicas' Rada Tilly line. See the Comodoro Rivadavia page in Chapter 6 for details of this line.
The above photo shows the turntable resting in less than splendid isolation in 1992 (3). At one time the intention was that it should be preserved but whether it has survived the creation of the new bus station on the station yard site is not clear.
Immediately east of the station was the new 1928 muelle and harbour. The construction works for this are covered mostly in Chapter six. The port eventually had its own locos and rolling stock, mentioned on the next page. In this view, taken in February 1943, the giant hammerhead crane is unloading broad gauge platform wagons from a lighter. Smaller mobile steam cranes and a port loco are a little further back. The 75cm. gauge tracks are also visible. In the far distance Cerro Chenque rises above the town.
The broad gauge after leaving the station immediately turns north along the narrow coastal strip below the hills.
Above is the early muelle that was shown under construction in an earlier picture. By now a number of buildings have grown up around it, but there is still no sign of any harbour works in the background so the date must be before the mid 1920s.
The 12M class pacific in the photo above is somewhere near Km. 3 (Barrio General Mosconi). The suburbs of Comodoro Rivadavia along the old railway route are often still known by their old line distances from the terminus. The station below may be that at Km. 3, or possibly Km. 5 before the railway workshops developed. Km. 3 initially had a short wooden muelle with a single line of broad gauge track upon it. However, it was later replaced by a steel construction carrying a double line of 60cm track.
The smaller stations were by no means as solidly built as the main terminus. Below is the building at Km. 5, though taken after the tracks had been lifted.
Eventually short branches were built from Km. 8, Empalme Astra, to access the oilfields at Astra and at Comferpet. The latter name is an abbreviation of the developing company 'COMpania FERrocarrilera y PETroleo'. A large scale map of Comodoro Rivadavia is in an appendix page. A pacific, the mainstay of the line's power, waits at Astra for a train of oil tanks to be loaded. Judging by the men on the tender top it appears that the loco is also taking on fuel.
After Empalme Astra the mainline turns inland past the aerodrome and eventually leaves the oilfields behind. The countryside is somewhat more undulating than that on the other broad gauge lines and by Holdich station, 31.7km. from the coast, the rails are 2,474ft. above sea level.

The rails were of 31 or 37 kg, per m, laid on wooden sleepers with mostly gravel or earth ballast. There were nine bridges, of up to 20m. length. Like the other lines, water for locomotive and other purposes had to be raised from underground using windpumps.
Visitors in the summer, seeing the hot dry windy plains of Patagonia, rarely consider what conditions can be like in winter. These two photos illustrate what the railway had to cope with. The upper picture taken in the 1930s shows a pacific on a newly cleared piece of line, whilst the lower shot, from the '50s or '60s shows a more difficult situation. Both photos were taken near Pampa de Castillo. Note the big square kerosene headlamp in the earlier picture, replaced by an electric lamp in the later one.
The line reached Sarmiento between Lakes Colhue Huapi and Musters in 1914. Whilst construction was abandoned at that point, it was fortunate that the terminus was in a productive agricultural area. That, combined with the demands of Comodoro Rivadavia as a market, ensured that there was rather more general traffic on offer than in the case of the Pto. Deseado railway.

Operations
It should be noted that, whilst oil remained the major freight, it was only carried for short distances, the oil wells being close to the coast. Timetables FC Patagónico 1948 Tickets A later re-organisation The World of South American Steam, published in 1973, suggested that all passenger services were then worked by railcars, with freight services operating perhaps twice a week. By 1975 it was clear that steam was only operating about once a week when a ship arrived. Loco no. 362 was the only regularly used engine at that time (5). Nevertheless there were still 120 employees on this railway! Closure The main station building in Comodoro Rivadavia exists and is currently (2001) being restored. The mixed gauge turntable may also survive as a monument to the 1953 disaster on the 75cm line to Rada Tilly. The stations at Escalante, Pampa de Castillo,Km 11 and Colhue Huapi were reported intact in 1997, whilst those at Km 96, Cañadon Lagarto, Valle Hermoso and Km 162/3 (Enrique Hermitte) were not so lucky (6). Sarmiento station was destroyed by fire in 1994. Additional photos Anyone interested in old photos of Comodoro Rivadavia should also visit Miguel Fiordelli's website.
