Talgo Pendular

The Talgo Pendular (Talgo IV and Talgo V, also VI & Talgo 200 or 6th generation), introduced in 1980, created the "natural tilting" train, using a passive system that tilts the carriages with no need for electronic sensors or hydraulic equipment. The wheels are mounted on mono axles between the carriages, and sitting on top of the mono axles are suspension columns. The carriages are attached to the top of the suspension columns and swing outwards as the train goes through a curve. In 1988, a Talgo Pendular was used on trials for

The trains were developed for Renfe and classed initially as S-130H, later as S-730). They are rebuilt from existing Talgo 250 trains.

Talgo 350 HSR

The Talgo 350 entered service as the Renfe AVE Class 102 marking the company's entry into the high-speed train manufacturing market. Tests with the prototype commenced in 1994, and Talgo 350 trains have been operating at a top commercial speed of 330 km/h on the

Talgo XXI is a project for a high-speed diesel-powered train, that operates in push-pull with one or two

s and Talgo VII intermediate cars. The North American version has four-axle power cars in compliance with United States FRA regulations. Only one train in compliance with European UIC standards has been built to date. Talgo reported that the Talgo XXI attained on the Olmedo-Medina del Campo high speed experimental line on 9 July 2002, which led to a claim for the world speed record for a diesel train. However, this claim was never proven. After the test runs the train was sold to the Spanish infrastructure authority ADIF as a measuring train for high-speed lines. Possible specs are: * Two MTU 12V 4000 R64 engines (two power cars configuration) or one MTU 12V 4000 R84 engine (one power car configuration), up to 1,800 rpm, high-speed diesel, Euro IIIB compliant with

The system uses underfloor traction in the front and rear vehicles, with the intermediate carriages having the Talgo Pendular system (which cannot use motored axles on the axles corresponding to the system). Starting with the concept stage in 2009, it began dynamic testing on the Spanish high-speed network in 2014, and was approved in May 2016. It won its first major contract in November 2016, for the Mediterranean corridor in Spain, and its link to Paris.
