![]() ![]() History ĭouble deck carriages date to at least as early as the second half of the 19th century. In some countries such as the UK new lines are built to a higher than the existing structure gauge to allow the use of double-deck trains in future. ĭouble deck cars may not be usable in countries or on older railroad systems with low loading gauge, most notably the majority of the British railway network. The increased dwell time makes them most popular on long-distance routes which make fewer stops (and may be popular with passengers for offering a better view). ![]() However, a bi - level train may take longer to exchange passengers at each station, since more people will enter and exit from each car. ![]() ![]() A bi - level car may carry up to about twice as many as a normal car, if structure and loading gauges permit, without requiring double the weight to pull or material to build. The use of double-decker carriages, where feasible, can resolve capacity problems on a railroad, avoiding other options which have an associated infrastructure cost such as longer trains (which require longer station platforms), more trains per hour (which the signalling or safety requirements may not allow) or adding extra tracks besides the existing line.ĭouble deck trains are claimed to be more energy efficient, and may have a lower operating cost per passenger. Czech Railways Class Bdmteeo294 in Kolín, Czech Republic.Ī bilevel car ( American English) or double-decker coach ( British English and Canadian English) is a type of rail car that has two levels of passenger accommodation, as opposed to one, increasing passenger capacity (in example cases of up to 57% per car). ![]()
