Stadler Rail AG is a Swiss manufacturer of railway rolling stock, with an emphasis on regional train multiple units and trams. Stadler has been building trains for 75 years for customers who count on reliability, precision and first-class service. Every step of the way, we do our best to make sure that wherever they are in the world, passengers get to their destination safely, quickly and in comfort.
One recent success for Stadler was being awarded the tender to supply 30 Tango LRVs to the third largest city in the Czech Republic, Ostrava. Tango LRVs are highly adaptable, which make them ideal across a variety of environments. However, it also meant that many options and obstacles needed to be considered by both Pyrotek’s and Stadler’s design engineers to make the project come together. Working with Stadler’s design team in Prague, the design presented a challenge to both companies.
The low floor design of Tango trams meant it had to withstand high impact and seal penetrations of the floor from the surrounding elements. The original design was to use metal sheeting and mastic sealants, but both of these items added cost and increased the design weight of the train.
Stadler needed to meet the strict weight requirements for the metro‐bound carriages while still providing long‐term protection to the exterior of the carriage and reducing noise and vibration transmission to provide a quieter ride.
The solutions
The project required an underbody coating, with high durability, and weather, stone and chip resistance, which meets the latest fire code and has a low environmental impact. Developed especially for transport and industrial applications, Decidamp SP500 effortlessly met Stadler’s weight restrictions whilst providing exceptional vibration damping.
Over ten months of rigorous testing and trialing of Decidamp SP500, the design team of Stadler were happy to re-design the flooring system to remove the original heavyweight solution and opt for a more efficient, easier, and cost-effective solution by using Decidamp SP500.
One critical factor in Stadler’s decision to specify Decidamp SP500 for their project was the relationship and trust built through the comprehensive consultation offered by Pyrotek’s team of research and development experts, who ensured that every outcome was met. This included problem-solving initiatives on the custom trams, technical data, and projections, as well as investigations into water resistance.
The results
The Tango project was completed in 2019, with a further contract between Ostrava and Stadler for more tram fleets to be produced. The strong, successful collaboration between Stadler and Pyrotek will continue with Decidamp SP500 specified for underbody protection in Stadler’s next fleet rollout. Stadler staff were supported in training for application techniques, as well as ongoing technical and personnel support by Pyrotek’s team, to ensure a smooth finish to the project.
