At Promens Zlín, we apply our expertise in manufacturing plastic components for rail vehicles to the production of interior window panels for the Škoda 49T trams operating in Bergamo, Italy. Projects of this type require the perfect combination of high-quality materials, precision manufacturing, compliance with strict railway safety standards, assembly capabilities, and reliable logistics.

For the Czech manufacturer of trains and trams, Škoda Transportation, we produce large-format interior window panels that are now part of the modern tram fleet serving the city of Bergamo.

The Challenge: Interior Window Panels for a Modern Tram

Interior components for rail vehicles must meet demanding requirements for safety, durability, and visual appearance. At the same time, they are manufactured in series production, where repeatability, process stability, and reliable delivery performance are essential.

For projects like this, Škoda Transportation places particular emphasis on:

The largest window panel for the Škoda 49T tram measures 2,074 × 1,724 mm.

The Solution: Thermoplastic Window Panels and Optimized Manufacturing Processes

Our solution builds on extensive know-how gained from manufacturing interior components for train units and other tram projects. Instead of traditional composite materials, we use thermoplastics manufactured using vacuum forming technology, providing a more efficient and sustainable solution for rail interior applications.

Thermoplastics offer several advantages for rail vehicle interiors:

Vacuum forming production at Promens Zlín.

Modular Tooling for Better Material Utilization

Another key part of the solution is optimizing tooling and material utilization. For this family of window panels, Promens Zlín developed a modular forming tool with a movable partition, allowing efficient production of different panel sizes while maximizing material efficiency.

The modular tooling solution helps to:

The window panels for the Škoda 49T tram are an example of a tailor-made solution that successfully meets demanding targets for cost, component weight, fire performance, and the replacement of traditional composite materials with thermoplastics.

Assembly and Preparation for Final Installation

As with many other rail vehicle projects, our scope of supply extends beyond thermoforming. It also includes a range of downstream operations such as surface finishing, bonding of seals and mounting elements, quality inspection, packaging, and preparation for shipment.

Bonding operations for rail vehicle components are carried out at our certified production facility in Zlín 2 in accordance with EN 17460:2022 – A2, ensuring consistent quality and compliance with railway industry requirements.

The Result: Rail Industry Expertise Applied to an International Project

The Škoda 49T project for Bergamo demonstrates how expertise in developing and manufacturing plastic components for rail vehicles can be successfully transferred across different vehicle platforms and international markets. By combining advanced vacuum forming technology, certified downstream processes, and reliable logistics, Promens Zlín delivers complete manufacturing solutions that meet the demanding requirements of the rail industry.

If you visit Bergamo, Italy, you can experience the new Škoda 49T trams in operation and see the results of our collaboration with Škoda Transportation. Among the interior components are our thermoformed window panels, measuring up to 2,074 × 1,724 mm.
