History
Interior of a 100 Series car after refurbishment

The 100 Series was initially purchased for use on Line A to replace the ageing La Brugeoise cars, however they ended up replacing the slightly newer Siemens-Schuckert Orenstein & Koppel cars which were allocated to Line D instead.

Originally, the purchase consisted of 80 cars for a total of 16 trains made up of 5 cars each, due to the shorter platform length on Line A. However, 16 more 100 Series cars were purchased up until 2009, making a total of 96 cars and allowing each train to have 6 cars, making full use of the line's platforms.[2]

In 2015 the cars began to receive a mid-life refurbishment, primarily to add air conditioning, but also incorporating enhancements to the interior such as improved lighting and new upholstery.[3] Despite enjoying a successful service life, they are also the noisiest cars on the network.[4]

Between 2017 and 2019 New Alstom 300 Series cars replaced the Fiat-Materfer cars and serve alongside the existing 100 Series cars.[5]
