Night train traffic can be found all over Europe, although its intensity varies between countries. There are many different types of night trains offering a diverse range of services, from high-quality trains with in-cabin catering and spacious private accommodation, to low-quality trains with only the most basic facilities. Night train traffic struggles with low profitability as a result of high personnel costs, low carriage capacity and low intensity of use as they can only be used at night. Moreover, railways in general and the night trains in particular have an image problem. There are many advantages of using night trains, such as the cost and time savings associated with travelling during the night or starting and ending the trip in the centre of the city.(...) The paper and especially the results of the survey point out the advantages of night trains as well as room for improvement. Night train operators will need to enhance their services and marketing strategies in order to hold their market share and increase demand.
