CFL Class 2400 and 2450 are a series of electric multiple units of the Coradia Max type built by Alstom for the Luxembourg National Railway Company, CFL, which is the first customer for this double-decker version (only one deck for the intermediate motor cars, with the roof occupied by technical equipment).

On 18 December 2018, the CFL signed a contract with Alstom for the delivery of 34 double-decker regional trains.^[1] The €350 million order^[2] included 22 three-carriage ‘short units’ (Class 2400) and 12 six-carriage ‘long units’ (Class 2450). Deliveries were initially scheduled to take place between December 2021 and December 2024, but due to the COVID-19 pandemic, they were postponed from February 2023 to December 2025.

The trains, which operate in Luxembourg, France and Belgium,^[3] are due to replace all of the CFL’s Class 2000 railcars, built between 1990 and 1992, and increase the seat capacity of its fleet by nearly 50%.^[3]

The first train, number 2410, entered service on 29 September 2024.^[4] The first Class 2450 train entered service on 19 January 2026,^[5] with the entire 2400 and 2450 fleet due to be delivered by late 2026.^[6]

As of 2025, Class 2400 trains are used on the following connections:^[7]
