In 1890 he presented his cableway in Switzerland, a country very interested in that transport owing to its geography and which was already coming to use cable cars for bulk transport, but Torres's project was dismissed, allowing certain ironic commentary from the Swiss press. In 1907, Torres constructed the first cableway suitable for the public transportation of people, in the mount Ulía in San Sebastián. The problem of safety was solved by means of an ingenious system of multiple support cables. The resulting design was very strong and perfectly resisted the rupture of one of the support cables. The execution of the project was the responsibility of the Society of Engineering Studies and Works of Bilbao, which successfully constructed other cableways in Chamonix, Rio de Janeiro, and elsewhere.
