Wikipedia: "The Talgo Pendular (Talgo IV and Talgo V, also VI & Talgo 200 or 6th generation), introduced in 1980, created the "natural tilting" train, a tilting train system that is passive and does not need electronic sensors or hydraulic equipment to move the carriages.
The wheels are mounted on monoaxles between the carriages. Sitting on top of these monoaxles are suspension columns. The carriages are attached to the top of the suspension columns and swing outwards when the train travels round a bend, thereby giving the illusion to the passengers that the train is tilting into the bend."
