In its heyday the Trans Andean Express ran from Valparaíso to La Paz via Antofagasta the train was a 12car luxurious train took 2 days to connect La Paz to the pacific. However Air travel, the rise of buses and the train being undercut by local railbuses would eventually spell its demise by 2002. At the time of our first visit in 1991 the train ran once a aday with an 08:00 from Antofagasta as train 121 and 20:00 as train 122. By this time the train was equipt with a 4-8-2 Mountain type engine of ether Alco or Mitsubishi Origin. At this stage of the services exisitance it functioned nearly as a toursit train . On this day our soundteam decided to listen on the sounds of the engine as it assendend Bishops Pass from its stop at La Engorda.
After the night of planning and working with the Ferroand staff we were given the go ahead for us to do a cab ride with train being hastly outfitted in sound gear. Our hope was it would be used in stock effects for future blockbuster movies.Microphones were strategically placed to capture every nuance—the hiss of steam, the rhythmic chug of the pistons, the engineer’s commands, and the echo of the whistle through the mountain passes.
This wasn’t just a railfan’s dream—it was a professional endeavor aimed at creating high-fidelity sound effects for use in future blockbuster films. The unique acoustic environment of a steam locomotive climbing the Andes offered a rare and powerful soundscape, rich with cinematic potential. The team’s goal was to preserve these authentic sounds before they vanished with the decline of steam operations in the region.
The rhythmic chuffing of the steam engine, the echo of the whistle against the mountain walls, and the metallic clatter of wheels on rail created a rich soundscape that told a story of the last steam haulled passinger trains in the western hemesphere. It was a moment where history, technology, and nature converged—an auditory tribute to a bygone era of rail travel.
