EURODUAL is a series development platform for hybrid electric locomotives launched by Stade to build its "most powerful" locomotive family. Since the announcement of the development plan in 2017, Stade has developed a series of high-power multi-system hybrid electric locomotives including EURODUAL, EURO6000, EURO9000 and 99-class dual-mode locomotives specially designed for Britain based on EURODUAL platform. Most of the EMUs on this platform are Co-Co axle type, which adopt diesel and electric hybrid dual power. The top speed is in the range of 120 km to 160 km, and the starting traction is as high as 500kN, among which the rated power of EURO6000 can reach 6.2 MW. These locomotives generally adopt multiple power supply systems such as 25 kV AC and 1.5 kV DC, which can meet the customized requirements of different customers and meet the actual operation requirements of corresponding lines. EURODUAL series locomotives adopt compact design, lightweight single body structure, and apply the most advanced adhesion control system and bogie technology to effectively reduce wheel-rail wear. Among them, EURO9000 is equipped with the latest generation of vehicle control system, advanced remote diagnosis system, modern maintenance system with optimal service interval, and central buffer automatic coupler specially designed for digitalization. Class 99 locomotive adopts the latest generation of innovative three-stage converter topology, which ensures high reliability and optimal energy consumption. The new locomotive has friendly environment characteristics, and the internal and external noise generated by operation is very low, and it has the advantages of high transportation capacity and low energy consumption.

In May 2017, Stade first outlined the development plan of its EURODUAL series of electric diesel locomotives at the Transport Logistics Fair held in Munich, and launched the EURODUAL six-axle dual-mode locomotive. This locomotive can be used for both passenger and freight transportation. It has both electric drive and diesel-electric drive. It can be used on electrified and non-electrified railway lines, especially without electrification, so as to meet the operation requirements on secondary freight routes, which is the development purpose of EURODUAL. The EURODUAL locomotive platform can provide operators with greater flexibility. For the restrictions faced by different markets, operators can order EURODUAL locomotives with different configurations. Previously, German freight operator HVLE, as the first customer of EURODUAL, ordered 10 EURODUAL six-axle locomotives from Stade in March 2017; In July 2018, VFLI also ordered 13 EuroDual dual-mode locomotives from Stade; In August 2018, European Loc Pool AG (ELP) acquired the first batch of 10 EURODUAL locomotives, of which 8 will operate in Germany and 2 will operate in Norway and Sweden. At the end of 2018, ITL Eisenbahngesellshaft Railway Freight Company of Germany also ordered four EURODUAL locomotives, which were deployed in Germany for heavy-duty freight transportation with a maximum running speed of 120 km/h.

In July 2020, Captrain Spain ordered 11 EURO6000 six-axle multi-system electric locomotives from Stade, among which five locomotives will have a running track gauge of 1435mm, which can be certified to run in Spain, France and Luxembourg. As these locomotives are intended to be used in the North Sea-Mediterranean Mediterranean and Atlantic All-European Transport Network (TENT-T) corridor. The locomotive can pull heavy freight trains with a total weight of more than 1800t, and the other six locomotives will be put into operation in Spain's 1668mm gauge network, which will be used to pull heavy freight trains on electrified routes, especially the Pajares baseline tunnel, which is powered by 25kV 50Hz power supply. As one of the EURODUAL series, EURO 6000 locomotive adopts three-voltage design and can operate in AC (25 kV) or DC (3 kV and 1.5 kV) electrified system. In August, 2021, Stade Company was ordered by Renfe, a Spanish state-owned operator, for 12 EURO6000 freight locomotives. The multi-system locomotive is designed to run on Iberian gauge, capable of towing 1800-ton trains and providing better and high-capacity transportation services. At present, Stade has sold nearly 100 Euro 6000 locomotives with different configurations, and its running lines include Spain, France, Belgium, Germany, Sweden, Norway and Turkey.

In 2019, Stadler received the first order for EURO9000 locomotive from European Railway Company (ELP). EURO9000 is a new hybrid multi-system freight locomotive improved by Stade on the basis of EURO4000 locomotive, which is equipped in six countries including Germany, Austria, Switzerland, Italy, the Netherlands and Belgium, and is suitable for the whole of Europe.

In April 2022, GB Rail freight, British leasing company Beacon Rail and Stade signed an agreement to order 30 99-class six-axle electric-internal combustion dual-power locomotives, which are expected to be put into use in 2025. The 99-class dual-mode locomotive is designed based on Schneider's previous EURODUAL six-axle dual-mode locomotive, which is especially suitable for British loading gauge and specifications. It aims to replace EMD 66 diesel locomotives from ports such as Felixstowe to logistics hubs, and is expected to reduce emissions per trip by about 50%. In April 2023, Stadler formally signed a service agreement with British Railway Freight Company for 99-class dual-mode Co 'Co' locomotives, which will become the first batch of electric-diesel locomotives capable of pulling heavy goods on trunk lines in British railway network. Up to now, ELP has purchased 30 EURO9000 locomotives and provided comprehensive service lease agreements to European railway freight operators from different countries.
