There currently are a variety of options to travel by night train from Dresden (Germany) to Frankfurt am Main (Germany), taking between approximately 6 and 8 hours: Namely the EN 40458 and the LE 232. These lines are operated by ÖBB and Leo Express.
The Austrian Federal Railways (ÖBB) operate the Nightjet and Euronight trains (the latter together with other national railway agencies).
The ÖBB usually offer four types of carriages in their night trains: seats, couchettes, Mini Cabins, and sleepers.
While seats are only for the bravest, couchettes, Mini Cabins, and sleepers offer a more comfortable journey. The couchettes usually feature simple and rather narrow berths, while the Mini Cabin provides a compact private space for one person. Two adjacent Mini Cabins can be combined for couples. Sleepers boast beds with duvets and pillows and sometimes even a private bathroom. Couchettes can hold up to six people. The Mini Cabin is a private space for one person – two adjacent Mini Cabins can be connected for traveling together. Sleepers are private compartments for one to three people.
Sleepers may include a private bathroom or shower, or sometimes just a sink. The Mini Cabin bridges the gap between couchettes and sleepers, offering solo privacy at a lower price point.
Leo Express is a Czech private rail operator. Its only true night train runs several times a week between Frankfurt and Przemyśl via Erfurt, Leipzig, Dresden, Prague, Ostrava and Kraków, with couchette and seating cars. The overnight trains between Prague and Warsaw and from Prešov to Prague have seats only, and a night bus connects Lviv with Kraków.
The Economy Sleeper is a berth in a mixed 4-person couchette compartment. Women and women travelling with children under 10 can choose the Economy Sleeper Lady compartment instead. A small breakfast and a kit with two bottles of water, earplugs and an eye mask are included.
You can choose between Economy, the basic class with Wi-Fi and a table at every seat, Economy Plus with leather seats and some drinks included, Business in a separate section with refreshments, and Premium – a quiet six-seat compartment with reclining leather seats.
