The Talgo II was built by ACF in 1951. The Talgo III was equipped with a steering truck started in 1963.
The fourth Talgo was called “Talgo Pendular” and had a pendulum mechanism introduced in 1988. In 1994 Amtrak brought the train to the U.S. and began test runs between Portland and Seattle (and Vancouver), and it later became the Amtrak Cascades.
The model was made by Electrotren and the 1994 Amtrak train was imported by E-R Model Importers.
