Double-Decker Coaches, General

HEROS offers double-decker coaches of types DBuza and DABuzfa in models 778 and 760 for regional transportation.

The essential idea behind the double-decker coach (also called a gallery car) is to be able to offer more passengers a seat on the same length of train on the track by using the same area of the vehicle on two stacked levels.

The crucial requirement for this is a minimum clearance outline which leaves sufficient space. One of the most frequently used clearances is the EBO G2 clearance or the similar UIC-C clearance. Here, up to 4650 mm above the rail level is available and the space offered in the passenger space is generous. These clearances are widespread in Eastern and Central Europe. HEROS offers double-decker coaches only for the EBO G2 clearance or comparable.

There are even double-decker coaches for the UIC505-1 clearance with up to 4280 mm above the rail level. Here there is a significant reduction of the height of the passenger room compared to single deck vehicles. Vehicles which implement this are frequently very specially developed for this use and often not well-suited to other applications.

Double-decker coaches have, on the one hand, the advantage of offering more seating than many single-decker vehicles, but on the other hand the disadvantage of offering fewer comfortable standing places. Therefore, these coaches are often used when platform lengths are limited and many passengers are to be offered seats.

There is a highly reduced noise level in the upper level of double-decker coaches and only rarely a draught, even when the boarding doors are open. Therefore, it can be very pleasant travelling in the upper level. In the double-decker coaches from HEROS, the upper level also offers large windows and thus a good view of the landscape and a pleasantly bright interior.

The double-decker coaches from HEROS also have wide boarding doors and large vestibules or boarding areas, so that the passenger exchange at the stops takes place quickly, although some of the passengers are exiting from the upper level.
