Alstom's Metropolis family of electric multiple units is highly adaptable; the basic body can significantly vary in size between small, medium and wide configurations to meet a variety of client's needs.

[1] The propulsion system incorporates the ONIX (ONduleur à Intégration eXceptionnelle) or OPTONIX VVVF drive with IGBT transistors that control asynchronous three-phase alternating current (AC) traction motors.

[1] For ease of maintenance, the Metropolis is compatible with an internet-delivered TrainTracer tool, which monitors major components of each train and can display condition information in real-time to depots and operational control centres alike.

[1] A specialised glass named Climavit is used for the windows, it is supplied by the French manufacturer Sekurit Saint-Gobain; amongst its claimed benefits is a reduction in the typical internal noise level by five decibels.
