Prague, Czech Republic – Škoda Group has initiated comprehensive aerodynamic testing of its newly developed 26 EV train units, designed for regional transportation services operated by Arriva. The tests,currently underway at the Research Society of Aerospace facility in Prague’s Letňany district,aim too validate the stability and performance of these trains at speeds reaching 200 kilometers per hour.
Advanced Testing Methodology
A meticulously crafted 1:25 scale model of the train’s leading car is being subjected to airflow speeds of up to 75 meters per second – equivalent to 270 kilometers per hour. Researchers anticipate conducting thirty distinct tests, with the resulting data informing certification processes and optimizing the train’s design for real-world operation. The aerodynamic tunnel, a historic structure dating back to the 1930s, provides a controlled habitat to assess the train’s response to various atmospheric conditions.
“It is indeed a low-speed laboratory,it is our second oldest building in Letňany,” stated Jan Červinka,a researcher involved in the testing. He oversees four aerodynamic tunnels, with the current facility being the largest, measuring three by three meters and capable of simulating speeds up to 90 meters per second.
the model itself is a composite of aluminum, plastic, and wood, with a hollow interior housing sophisticated measuring instruments. Emanuel Mergl from the Research Institute of Rail Vehicles (VÚKV) explained, “The properties of the head car are measured and the effects of overflowing the vehicle by air gust. We verify the geometry and shape of the vehicle and the suitability of their design.” The tests will also examine the impact of side winds on train stability and energy consumption.
Future Deployment and Capacity
The Škoda 26 EV units are slated to enter service on the EX6 Prague – Plzeň – Cheb and R16 Prague – Plzeň – Klatovy / Železná Ruda lines beginning in December 2028. They will replace existing Czech railways sets under a 15-year contract. The fleet will comprise 16 three-car units (with 224 seats each) for the R16 line and 6 four-car units (with 315 seats each) for the EX6 line.
Notably, the units are designed for flexible configuration, allowing up to three units to be coupled together, creating a train with a potential capacity of 900 seated passengers. arriva has allocated approximately CZK 7.2 billion for the procurement of these new trainsets.
| Train configuration | Number of Units | Seating Capacity (per unit) | Line |
|---|---|---|---|
| Three-Car | 16 | 224 | R16 |
| Four-Car | 6 | 315 | EX6 |
Production and Delivery Timelines
Daniel Adamka, CEO of Arriva, emphasized the company’s commitment to both economic and ecological considerations throughout the production process, stating, “We also go through the process of production as a customer. We want the vehicle to be economic and ecological. Therefore,his aerodynamics is not only in these respects a very crucial part of the project of its creation.”
Škoda Group has already begun sourcing aluminum for the construction of the trains. According to Richard Škvarálo, head engineer at Škoda Group, the company is currently focused on vehicle projection, involving the creation of 3D models and detailed designs for key components like air conditioning, brakes, and doors. The design phase is anticipated to commence in early 2026, with gross construction beginning mid-year and final assembly scheduled for completion by the end of 2026.
Initial testing on a dedicated track in pilsen is planned for early 2027, followed by further trials at the VUZ test circuit in Velim later that year.
The Growing Importance of Aerodynamic Efficiency in Rail Transport
Aerodynamic efficiency is becoming increasingly crucial in modern rail transport. Reducing drag not only lowers energy consumption, contributing to sustainability goals, but also improves ride comfort and reduces noise pollution. According to a 2023 report by the European Environment Agency, rail transport is already significantly more environmentally friendly then road transport, and advancements in aerodynamic design can further enhance its positive impact. Innovations like streamlined train nose cones and underbody fairings are being implemented globally to minimize air resistance and maximize performance.

Skoda Tests New Train Model for arriva in Aerodynamic Tunnel: An Insight into Groundbreaking Innovations
Aerodynamic Testing: The Core of Efficiency
Skoda Transportation,a leading European manufacturer of rail vehicles,is currently undergoing rigorous aerodynamic testing of a new train model destined for Arriva,a major European public transport operator. This testing, conducted within a specialized aerodynamic tunnel, focuses on optimizing the train’s performance, reducing energy consumption, and enhancing passenger comfort. The core principle revolves around minimizing aerodynamic drag, a notable factor impacting train speed and efficiency, especially at higher velocities.
This isn’t simply about speed; it’s about lasting transportation. Reducing drag directly translates to lower energy demands, aligning with growing environmental concerns and the push for green mobility solutions. Skoda’s commitment to innovation in rail technology is clearly demonstrated through this advanced testing phase.
The Aerodynamic Tunnel: A Controlled Environment for Optimization
The aerodynamic tunnel simulates real-world operating conditions, allowing Skoda engineers to meticulously analyze airflow around the train. Key areas of examination include:
