Getting the coal to the coast

That there were coal deposits to be mined in the far south, was known back in the 19th century. On the Chilean side of the border there were small mines near Punta Arenas as is described on the Mina Loreto page. Other deposits have been listed on the Overview page, together with a number of schemes for railways to aid in their exploitation.

Whilst there were deposits on the Argentinian side of the border they suffered from the difficulty of not being able to get the product out easily without crossing Chilean territory. This had also been a difficulty in the development of agriculture further north, in for example the Río Baker area. I suspect this was the reason why it was not until the 1940s that exploitation started in the Río Turbio district of Santa Cruz province.

Coal from Río Turbio
It was the war-time shortage of coal that prompted the new excavations. Argentina had relied heavily on Welsh coal that rapidly became unavailable as the U-boat war developed. The country experienced a serious fuel crisis, despite increased oil production and the use of wood and other 'biomass' fuels for locomotives up in the north. At any rate Río Turbio was producing coal by 1943, under the supervision of a new division of the state petroleum producer, YPF, known initially as the División Carbón Mineral, and later as Combustibles Sólidos Minerales. At this stage costs were vastly higher than receipts but this was accepted as a necessary stage in the development of a new industry.

Sentinel steam wagons
The next difficulty was to get the coal out to an Argentinean port from whence it could be shipped north. In 1949 retired Admiral Juan A. Martin of the Argentinean Navy was quoted as saying that 'Under no circumstances would Río Turbio coal be shipped out via Puerto Natales' (1). For the first few years petrol lorries were used, consuming incidentally more energy than they actually carried and often being abandoned on the road for lack of parts to repair them!, but in 1950 they received a fleet of 'S' type undertype (ie with cylinders below the frame) steam lorries from Sentinel of Shrewsbury, England. These were the last steam lorries to be built for commercial use anywhere in the world, and one commentator suggests that the Argentine state never completed the payments for them! (8). Under the technical supervision of a Mr. McKay from the Falklands they operated in convoys of 10-15 taking 12 hours for the journey to Río Gallegos (7). They were relatively modern in design but still used a substantial proportion of their load during the 320 mile round trip and it became obvious that only a railway would do the job properly. One of the Sentinels is preserved at Río Turbio, and another lies at Lujan zoo near Buenos Aires. They were known colloquially as 'los chufi'. Recent reports suggest that some of them remained in use until 1959 (6) (8).

A small coal washing plant was also brought into use in 1950, another stage in the transformation of an experimental facility into a practical production plant.

The surviving Sentinel lorry is shown below, as it was at the Río Turbio mining museum. The other photos show the Sentinel name cast into the undertype engine housing and the wheel hubs respectively.






The Sentinel wagon preserved at Río Turbio has recently been overhauled (2016) by Cromwell Engineering in Buenos Aires. The photo below shows it during that work. Its present location is not known.



Proposed routes
The first proposals had been to build a line via El Zurdo across to Santa Cruz. This idea was postponed when estimates of the coal reserves were reduced. However, in 1946 revised estimates of 100,000,000 tons provoked further thought. A new route was surveyed using the Río Turbio and Río Gallegos valleys. This was only two-thirds the length of the Santa Cruz line but a new port would be needed at Río Gallegos. The new course would also be less steep and would suffer less from blizzards (2) (6). A 1949 report suggests that the final change of plan was only made at a very late stage; this was possibly after additional survey work had proved that steep gradients would not in fact be necessary along the route to Río Gallegos. Earlier work by FCE engineers had suggested that a practical route could not be found (8). Land for sidings had been bought at Santa Cruz and in 1949 there were engineers there awaiting the 'go-ahead' on the original route (1).

The mine owners, at that stage Argentina's national petroleum company (Yacimientos Petroliferos Fiscales or YPF), cast around for an easy way to build the line. The solution was to use some of the 75cm. gauge equipment and stock that was still lying at Puerto Madryn, unused since the abandonment of the ambitious 1922 plans. 300km of 17.36 kg/m rail were available there, with another 90 km of similar material at Rio Grande for the Ministry of Marine's abortive Tolhuin railway.

Construction work
Given the Patagonian climate, all work had to be completed during the months of October to April. However, unloading of equipment onto the beach at Río Gallegos began in May 1950. 50,000 tons of equipment arrived in this way for Río Gallegos still had no port as yet (2). 250,000 broad gauge sleepers were sourced from the FCNGR, making 500,000 narrow gauge ones when sawn into two. A variety of fittings, such as point levers, also came from various parts of the newly-nationalised rail system.

Ing. Atilio Cappa was the engineer, an employee of the Ministry of Public Works. In a departure from traditional practice motor lorries were used to transport material beyond the railheads. By May 1951 all but two miles were complete, with the finishing touches made in September, after the worst of the winter.



What is possibly a posed photograph as there is no sign of a works train with sleepers and rails at the end of the track laid.


The formation has been completed by Vialidad Nacional, and now the railway squads from the Central Norte section of the new FCN Belgrano move in to lay the track. First the sleepers with pre-drilled holes for the rail spikes are dropped in position as precisely as possible by eye, a pinch-bar is used to slide it about if it is not quite right. Then four spikes are laid ready for the next step. The rails are carried from the wagon on the shoulders of the squad, dropped in place, loosely jointed to the rails already laid, and a start made to spiking them down. The spikes would not be driven home completely at this stage as it may be necessary to make minor adjustments to the positioning of the sleeper, before completing the driving home. While the track is nowhere near finished yet, it is good enough for the works train to use to bring up more materials. We thank Héctor Guerreiro for finding this view.

The Bahía Blanca North Western workshops played a major role in getting stock ready for the South. It re-gauged a number of wagons which had started life on the metre gauge Central of Chubut, and which had been lying unused in Puerto Madryn since the early 1930s. It also re-furbished the Ministry of Marine four wheel wagons, which formed the bulk of the initial rolling stock. It is remembered that these were treated differently from the routine work – all work was carried out in the open, and no drawings were prepared to show what work was required, nor any record or diagrams prepared for the completed work.

This view shows one of the 0-6-0Ts being loaded at the docks at Bahía Blanca. It had been taken to the Bahía Blanca North Western Workshops for a major overhaul before being shipped south. It is being lifted off an Estado flat wagon by the local broad gauge breakdown crane. The wagon next to it has already been re-branded into Roca after the nationalization of the FC Sud.


Incredibly there is a view of the 6-wheel brake van being loaded here as well. (10)


The third picture show a great many sleepers stacked ready for despatch. Broad gauge sleepers from depots all over the country had been taken to Bahía Blanca to be cut into two halves, before being shipped south. (9)




The two views show what was involved in bringing the Mitsubishi locos to the line. There were no dock facilities in Río Gallegos at the time. Here the landing craft has been beached, and men are busy at work preparing a temporary line to run the loco from the landing craft to the railway. It is likely that the landing craft was loaded at Bahía Blanca, the most southerly port which could deal with lifting the locomotive on to the ship, thus involving the shortest possible voyage. The source of this view is Facebook, with authorship as noted. (11a) [2480]




In this view the temporary line has been completed and the tender of № 105 is being drawn up the beach. It was taken from the same source. (11b) [2471]



These two black and white photos are of the first days of the line. The one above is supposed to be of the very first train to run right through - hauled by a Henschel 2-8-2 and made up mostly of four-wheeled wagons. The picture below was taken on the opening day, when the Minister of industry and commerce, Don José Constantino Barra, cut the tape to allow the first official train through in November 1951.


The opening
The formal opening was on 25th November 1951 (3). The railway was initially known as the Ramal Ferro Industrial Eva Perón (RFIEP or Eva Perón industrial railway line) which appropriately carried coal from the 'Yacimientos (mines) Juan Perón'. However, after the military coup in 1955 President Perón and his wife were not quite the flavour of the month and the railway was renamed the RFIRT, or Río Turbio industrial railway line.

A few wagon axlebox covers survive showing the original initials of the RFIEP. Observant readers will notice that this one was actually fastened on upside-down, as evidenced by the oil build up at the top as well as the dandelion top right!


The new line was laid with 17kg./m. rail from the stocks at Puerto Madryn (soon replaced with 24 and 32 kg./m.), and ten locomotives and a large number of wagons and cars were also shipped south from Puerto Madryn to operate the new link. The next pages describe the stock in detail.

Until a new muelle was opened at Río Gallegos in August 1952 all materials brought in and coal sent out had to use the beach. In fact the CSM, after first using the steamer Bahía Aguirre of the Comando de Transportes Navales ( a fleet auxiliary service supplying Patagonian establishments), purchased two tank landing craft from the US Navy.

The principal customer for the coal was the new San Nicolás power station in Buenos Aires province. There were others, and during the first few years the Perón government applied pressure to encourage the use of Río Turbio coal by for example the frigorifico in Pto. Deseado, but it was difficult to find willing private customers and throughout the life of the mine the vast majority of the coal has gone to government users.

As the railway gradually ceased to be the bottleneck limiting production, so output rose. A new coal washery opened in 1958 lifted throughput to 250 tonnes per hour. New ships were purchased, and at the same time coal moved out from under the shadow of the petroleum industry through the creation of Yacimientos Carboniferos Fiscales to take over the responsibilities of CSM including the mine and railway.

The route in detail
A detailed description of the features to be seen along the line can be found in Appendix 1. In summary, the route is 262km. long with ruling grades of 1 in 330 (0.3%) eastbound (loaded) and 1 in 160 (0.6%) westbound (empty). There were initially stations with passing loops every 15km. or so, but over the years many of these have become unmanned or even abandoned altogether. There are few big earthworks but there are three major river crossings. It must be emphasised that despite its narrow gauge, this was serious railway construction for heavy trains over a long distance.

Tracing the route using Google Earth
Readers who have the Google Earth program can right click (control-click on a Mac) on the following link:

El RFIRT on Google

Save the file to your desktop and double-click to decompress it. Open the folder and drag the KMZ file onto Google Earth's Places palette. You will now find that you have placemarks for each of the main locations along the route, and a path to enable you to 'fly through' the route as if in a helicopter. Select this and click on the start button to commence the flight.

RFIRT, Río Gallegos a Río Turbio A flight along the trackbed from Río Gallegos to Río Turbio.

Generally the route is clearer without the overlying vector path being checked and visible, but with the appropriate station placemarks checked. Flights or 'tours' in this website are best done with the Google Earth touring preferences set to a camera tilt angle of about 60 degrees, and a camera range of about 300m.

"Fly-throughs' on such long routes as this one can be extremely tedious unless the Google Earth preferences are set to a fairly high speed. If looking for a particular location you might be better advised to click on a named placemark. However, the monotony of following the trackbed across the bare pampa for hundreds of miles does at least give a clear impression of the problems of making such a railway pay its way.

The role played by areal photography in identifying previously unknown Roman army camps in the UK is well known, as is its connection with the Nazca lines in Peru. We discovered that Google Earth can be used in the same way, particularly in the arid parts of Patagonia, where vegetation does not grow rapidly over the surface and obstruct marks on it. Between El Turbio and Glencross stations we found what appeared to be a new alignment, extending about 2 km, in which the line was moved away from the río Turbio and straightened. There is no reference to this work being carried out in any of the published accounts of the railway.

It is not very likely that we would have spotted the divergence of the two lines had we been on the footplate, and there wouldn’t have been much chance either had we been walking the line at this point. There is a Facebook group Mi Río Gallegos which deals with the past of the town and its dependant countryside; an enquiry about the possible diversion of the line was made; a reply was quickly received, confirming that there had been a diversion, and explaining that it had been done as the original line was subject flooding from the adjacent river. This is a good example of the tools which are available to researchers nowadays, making distant investigations far more feasible and economic. (12)
