käytävävaunu

Käytävävaunu, also known as a corridor carriage or a walk-through carriage, is a type of railway carriage where passengers can move between carriages. This is achieved by providing a connecting passage, often with an accordion-like bellows or a flexible rubber enclosure, that seals the gap between the carriages.

The primary advantage of a käytävävaunu is the ability for passengers to move freely throughout the train. This can be particularly useful for passengers with young children, those who wish to visit dining or buffet cars, or simply to stretch their legs. It also allows train staff to move more easily for services or inspections.

Käytävävaunu designs have been employed in various types of trains, including passenger coaches, sleeping cars, and even some high-speed train configurations. The specific design and extent of the corridor can vary, with some offering a completely open passage while others might have more restricted access.

The development of käytävävaunu technology has contributed to passenger comfort and train operational efficiency. The ability to access different parts of the train without exiting and re-entering can enhance the overall travel experience for passengers and streamline onboard services for the crew.
