Sprague-Thomson was the name of the first rolling stock on the Paris Métro made completely of metal.

However, some Sprague-Thomson cars converted into work trains remained in service until 8 March 2011.

The RATP has preserved three Sprague train sets, only one of which is currently usable by passengers.

The historical train was abandoned in a secret tunnel from the mid-2010s,[1] then renovated during 2023.

The train was later displayed at Porte d'Auteuil for the centenary of Line 10.
