On 9 May 2023, RailAdventure signed a contract with Stadler, which will produce a single Euro6000 locomotive for the operator, with delivery by 2025. The locomotive will be used to pull special trains between Spain, France, Luxembourg and Belgium.
In addition to this, RailAdventure will add a second Siemens ES64U4 locomotive to its fleet. It will enable operations on the German – Slovenia / Italy corridor. The previous locomotive was purchased in 2019 and is authorised for operation in Germany, Austria, Czechia, Slovakia, and Hungary.
