Behind the cold dates of openings and closures, "Los Catalanes" hides a deeply human story of industrial ambition, backroom espionage, and an agonizing decline played out right on the tracks.

The Belgian Brain in the Shadows and the "Cement King"

Although the company operated in Catalonia, the money and strategy largely came from Brussels. The key player in its founding was Sofina (Société Financière de Transports et d'Entreprises Industrielles), a massive Belgian holding company that spent the first third of the 20th century buying up and unifying power grids and transport networks across Europe.

For the Belgians, the CGFC wasn’t just a train; it was the missing puzzle piece. They already controlled electricity production and the Port of Barcelona; with this narrow-gauge railway, they closed the loop to transport Berguedà coal and Súria potash without depending on the freight rates of their competitors (the French-backed MZA company).

On the local front, the driving force was Eusebi Güell (Gaudí’s famous patron), who desperately needed this train to move cement from his factory in Castellar de n'Hug (Asland) down to Barcelona. In fact, the tracks reached as far as Guardiola de Berguedà, and from there, an even smaller mining train (popularly called the Carrilet) climbed right up to the cement plant itself.

The Business Model: Minerals Paid for the Passengers' Tickets

The CGFC was never conceived as a public passenger service; that was merely a side effect. The real money was in heavy freight. The model was perfect because it worked both ways: trains rolled down loaded with coal, salt, potash, cement, and textiles from the industrial colonies along the Llobregat river toward the Port of Barcelona, and they headed back up packed with machinery and raw materials.

In the early years, passengers literally rode in coaches hooked to the back of cargo trains (known as mixed trains). They were agonizingly slow because the train stopped at every single station to load or unload crates, leaving passengers to wait patiently on hard wooden benches.

Trackside Anecdotes and Curiosities

• The Track Gauge Trap: The company chose the meter gauge (1 meter between rails) because the terrain was highly rugged, and narrow tracks allowed for much sharper, cheaper curves. However, this created a railway "island"—their trains could not share tracks with Spain’s main network (broad gauge). At Martorell, monumental bottlenecks formed where workers had to manually transfer cargo from one train to another.

• The Train That Brought the "Spanish Flu": A dark legend in the mining basin claims that in 1918 (during the preliminary maneuvers just before the company's official merger), the severe overcrowding in the tiny carriages between Manresa and Berga became a primary vector for spreading the deadly flu epidemic through the industrial towns.

• A Cinematic Line: The spectacular bridges over the Llobregat river and the vintage atmosphere the line preserved well into the 1960s and 70s made its stations and steam trains a favorite for filmmakers, serving as backdrops to recreate rural Spain in several movies.

The Final Days: The Agony of the Seventies

By the 1960s, the business model fell apart. Trucks began winning the battle on the roads, and the fatal blow came when the Berguedà coal mines started shutting down. Without coal to transport, the northern section of the line became a financial black hole.

The private company’s final years (1970–1977) are remembered with a sense of sadness. Due to a total lack of budget, maintenance was virtually nonexistent. Derailments were common because of the warped tracks, diesel locomotives broke down constantly, and delays became the norm. Workers performed genuine mechanical miracles, handcrafting spare parts in the Martorell workshops because there was no money left to buy them.

In 1972, the company dealt its first major blow: it closed and dismantled the historic section between Manresa and Guardiola de Berguedà. It was a devastating loss for the region, compounded by the construction of the La Baells reservoir, which was set to flood part of the old route.

The End: From Liquidation to a Public "Miracle"

By May 1977, the financial situation was terminal. Burdened with unsustainable debt, the CGFC announced it could no longer pay wages and would suspend all passenger services overnight.

However, there was no liquidation sale or scraping of the assets. Leaving thousands of workers in Barcelona's industrial belt stranded would have triggered massive social unrest during Spain’s delicate transition to democracy. The Spanish government intervened urgently through the state-owned FEVE (Ferrocarriles de Vía Estrecha) simply to keep the trains running while a handover was negotiated.

While the private company dissolved, its demise actually prevented a disaster. In 1979, the newly reborn Government of Catalonia (Generalitat) inherited this obsolete network. Instead of shutting it down, they launched a massive investment plan—replacing old tracks, doubling lines, and moving sections underground—effectively transforming a decaying mining train into the thriving Baix Llobregat metro system used today.
