Definitions

• the present invention relates to passenger rail vehicles.
• Mobility is an essential public service and passenger rail vehicles are an appropriate and environmentally friendly mobility solution.
• Passenger rail vehicles are generally known to be designed to have two decks and thus to be able to carry passengers on both decks. See for example US2636452A , EP642964A1 , or WO2019144538A1 .
• Such rail vehicles commonly known as double-deck rail vehicles, increase passenger carrying capacity by up to 50% over single-deck rail vehicles, thus, are more energy efficient and have a lower operating cost per passenger.
• double-deck vehicles are usually higher than 4 metres and cannot be used on railway lines with a low gauge (below 4 metres), and furthermore, due to their length and passenger carrying capacity, they are not profitable on low occupancy lines.
• low occupancy lines single-deck vehicles are used, but even then, it is difficult to make them work economically, because traffic on such lines is irregular, and some use only a few vehicles per day. Therefore, space optimization on these vehicles is essential to make these low occupancy lines profitable.
• the vehicle space is not adequately utilized.
• the space for transporting seated passengers is not optimized, and too much space is used for other purposes, such as storage areas for transporting objects (e.g. bicycles or luggage), location of electronic equipment, toilets, PRM (persons with reduced mobility) areas, etc.
• objects e.g. bicycles or luggage
• PRM personnel with reduced mobility
• the object of the invention is to provide a passenger rail vehicle, as defined in the claims.
• the invention relates to a passenger rail vehicle comprising a train unit mounted on at least two axles.
• the train unit comprises a front section, a rear section and an intermediate section arranged in longitudinal direction between the front section and the rear section.
• the sections are internally connected to allow the passage of passengers between the sections.
• the front section has a first passenger area with passenger seats and a first boarding area
• the rear section has a second passenger area with passenger seats and a second boarding area.
• Each boarding area has at least one door for boarding passengers onto the train unit.
• the middle section has a lower level and an upper level, the upper level is arranged in a vertical direction above the lower level, the upper level has passenger seats and the lower level has a storage area for storing objects, the lower level has a first height in a vertical direction not exceeding 1,85 metres, and the upper level has a second height in a vertical direction not exceeding 2,15 metres.
• the distribution of space for passenger transport and object storage is optimized, allowing the number of seats to be increased compared to a conventional single-deck vehicle.
• the storage area of the lower level allows the storage of objects such as baggage, bicycles, or parcel containers, which makes the rail vehicle particularly suitable for low occupancy lines, increasing the degree of flexibility for utilising the interior space.
