The Central Chubut Railway transformed Puerto Madryn from a remote landing place into the maritime gateway of the Lower Chubut Valley. Opened in 1889, the metre-gauge line connected the natural harbor with Trelew and later extended through the agricultural settlements of the valley. Its tracks carried produce, wool, passengers, mail and new residents until the system closed in 1961.
Why the railway was needed
The Welsh settlements along the Chubut River had developed irrigated agriculture, but moving goods to an ocean port remained difficult. The river mouth near Rawson was unreliable for larger ships. Golfo Nuevo offered a sheltered deep-water setting, yet Puerto Madryn and the valley were separated by dry steppe.
The railway solved that geographic problem. Construction began in the 1880s through a British-owned company, with Welsh, Italian, Spanish and other workers contributing to the line and the settlements around it.

Puerto Madryn: port and railhead
At Puerto Madryn, rail and sea met. Warehouses, workshops, worker housing and commercial services grew around the station and port. The railway helped create a permanent urban population and gave the city a role beyond the symbolic 1865 Welsh landing.
The former station now helps visitors read that urban history. It is associated with the Juan Meisen Ebene Historical Museum; opening hours and exhibition access should be confirmed locally before visiting.
Trelew and the valley connection
Trelew’s name means “Lewis’s town” in Welsh, referring to Lewis Jones, a central figure in the railway project. The settlement developed around the line and became a commercial center for the valley. From there, the railway network expanded toward Gaiman, Dolavon and farther west over time.
For a broader explanation of the agricultural landscape, read the site’s guide to the Lower Chubut Valley. The green irrigated corridor makes much more sense when seen as the inland half of a port-and-rail system.

What did the trains carry?
- Agricultural produce from the irrigated valley, including grain.
- Wool and livestock-related products from Patagonian ranching districts.
- Imported tools, construction materials and consumer goods arriving by sea.
- Passengers, workers, postal items and news between coastal and inland communities.
The railway did more than move freight. It compressed distance, encouraged immigration and connected communities whose daily lives had previously depended on carts and difficult roads.
Why did the Central Chubut Railway close?
By the mid-twentieth century, road transport had become increasingly important and Argentina’s railway policy was changing. The Central Chubut system ceased operating in 1961. Tracks were removed or absorbed into later urban development, but stations, alignments, bridges, machinery and place names preserve parts of the route.

How to follow the railway today
Puerto Madryn
Start at the former station area and connect it with the waterfront and port. This reveals why the city grew where it did.
Trelew
Look for railway heritage in the city center and local museums. Trelew is the clearest place to understand the line as an engine of urban development.
Gaiman and Dolavon
Former stations and railway corridors complement Welsh chapels, irrigation canals and agricultural heritage.
The site’s Gaiman guide provides the cultural context for this part of the route.
In my experience, the railway story works best as a landscape journey rather than a checklist of surviving buildings. Travel from the port across the steppe to the green valley and the original economic logic becomes visible.
A line that still explains the region
The trains are gone, but the Central Chubut Railway still explains the relationship between Puerto Madryn, Trelew and the valley. It linked ocean shipping with irrigated farms and turned separate settlements into a regional network—one whose geography travelers still follow by road today.
