Stadler KISS Double-Deck Trains: Railway Technology

This article explores the innovative design and technological advancements embodied in Stadler’s KISS (Komfort Innovativ Sicherheit Schweizerisch – Comfortable Innovative Safe Swiss) double-deck trains. The project aims to analyze the various configurations and operational parameters of the KISS trains, highlighting their adaptability to different railway networks and passenger needs. We will delve into the design features that maximize passenger capacity while maintaining comfort and safety, examining the technological aspects that contribute to efficiency and performance. Furthermore, we will review successful deployments across various European railway operators, providing a comprehensive overview of the KISS’s impact on railway operations and passenger experience. This analysis will contribute to a deeper understanding of the role of innovative rolling stock in enhancing railway transportation efficiency and providing a superior travel experience.

Design and Passenger Capacity

The KISS design prioritizes maximizing passenger capacity without compromising comfort or safety. Key features include a low-floor entry with sliding steps for improved accessibility, a generous 2-meter internal vertical clearance, and numerous doors (12 per side) for efficient passenger flow. The relocation of the HVAC (Heating, Ventilation, and Air Conditioning) system to the ceiling frees up valuable floor space, further enhancing passenger comfort. The Swiss Federal Railways (SBB) version, for example, boasts a 150m length, accommodating 535 seated and up to 1373 total passengers. Different configurations exist, including four-car and six-car versions, tailored to specific line requirements. The Austrian version, primarily designed for first-class passengers, demonstrates adaptability with a different seating capacity and higher maximum speed. This flexible design highlights the KISS’s adaptability to diverse operational needs.

Technological Advancements

The KISS incorporates state-of-the-art technology. The redundant propulsion system, featuring eight propulsion chains with water-cooled IGBT (Insulated Gate Bipolar Transistor) converters, ensures high reliability and performance. Air suspensions on the bogies contribute to a smooth and comfortable ride. The trains are designed for high speeds, with maximum speeds ranging from 160 km/h to 200 km/h depending on the specific configuration and operational requirements of the railway line. The incorporation of modern train control systems, such as ETCS (European Train Control System), ensures compliance with the latest safety standards and interoperability across different railway networks. The use of aluminum in the construction of the car bodies contributes to reduced weight, increasing efficiency and reducing energy consumption.

Operational Deployments and Contracts

The success of the KISS is evidenced by the significant number of orders received from various railway operators across Europe. Below is a summary of key contracts:
