Seven manufacturers expressed an interest in the contract and three - Alstom, CAF, and Stadler - submitted bids. Luxtram says that CAF achieved the highest score in both the technical and economic elements of the evaluation process and has therefore been selected for the final phase of negotiations.

Construction is expected to begin later this year on the route, which will link the city's main station and Place de l'Étoile in the city centre with the LuxExpo exhibition centre in the district of Kirchberg. The line will include a catenary-free section through the city centre.

The first vehicles will be delivered in early 2017 in time for the opening of the initial 6.4km phase between LuxExpo and Pont Rouge, which is scheduled for commissioning in the second half of 2017. Each vehicle will accommodate up to 450 passengers.

The budget for the 14-station line is estimated to be around €230.5m and the city has agreed to fund half of the cost with the remainder coming from the national government.
