Instead of having an extended terminal stop at Charles de Gaulle - Étoile, Line 6 trains depart quickly back round the loop and then stop for an extended period of time at Kléber, which has extra platforms and tracks to accommodate the arrangement.

It is used as a prolonged stop of trains before or after their passage at the terminus of Charles de Gaulle - Étoile depending on the necessary regulations and break times for the drivers.

The "commercial" terminus of Charles de Gaulle - Étoile is too constrained to be able to play this role effectively.

The light canopies are suspended and designed with crisscrossed metal slats, while beige ceramic tiles, aligned vertically (found only at Porte de Bagnolet and Gallieni stations on line 3), cover the walls of the platforms, the tunnel exits as well as the end of the vaults.

The advertising frames are metallic, and the name of the station is inscribed in capital letters on large, enamelled plaques.
