Copenhagen to Bologna by train

There is no direct train from Copenhagen to Bologna. The simplest rail route is Copenhagen to Hamburg, Hamburg to Munich, then Munich to Bologna over the Brenner route through Austria and northern Italy.

This is a long international journey, so treat it as a one-night trip rather than a day run. Route planners currently show the fastest connections at around 21 hours, with more typical journeys around 23 hours, but the exact answer depends on your travel date, engineering works, and how much transfer time you want.

The Best Route Is Via Hamburg and Munich

The cleanest daytime plan is Copenhagen, Hamburg, Munich, Bologna. It keeps the route on major long-distance corridors and avoids unnecessary detours through Switzerland or France.

Start at København H, also shown in English as Copenhagen Central Station. Take the direct DSB/Deutsche Bahn train to Hamburg Hbf. DB and DSB run five direct trains each way daily, with a sixth added from late March and seasonal additions in summer; the journey takes around five hours.

From Hamburg, continue south through Germany on Deutsche Bahn long-distance trains. Munich is the most useful transfer point because it connects directly with the Brenner route into Italy.

From Munich, take the DB, ÖBB EuroCity or Railjet service toward Innsbruck, Bolzano, Verona, and Bologna. ÖBB runs daily direct Railjet and EuroCity services on the Bologna, Verona, Bolzano, Innsbruck, Munich corridor. Some timings run through to Bologna Centrale; others work better with a change at Verona Porta Nuova for an Italian domestic train to Bologna Centrale.

The Overnight Route Via Innsbruck Is Often Easier

If you dislike spending a full day changing trains, use Hamburg as the break point and take the ÖBB Nightjet to Innsbruck. Nightjet runs a daily overnight service from Germany to Innsbruck, with departures from Hamburg and accommodation choices including seats, couchettes, and sleeping cars.

This version normally looks like this:

• Copenhagen to Hamburg by DSB/Deutsche Bahn.

• Hamburg to Innsbruck overnight by ÖBB Nightjet.

• Innsbruck to Bologna by DB, ÖBB EuroCity or Railjet over the Brenner route.

The overnight route is not a direct Copenhagen, Bologna sleeper. It is a useful way to turn the hardest middle section into a night on the train, then finish the Alpine crossing by daylight.

Tickets Are Usually Easier in Separate Sections

Search the full Copenhagen to Bologna route first. If a through fare appears at a sensible price with protected connections, that is the cleanest option.

If the through search is messy, split the booking into sections:

• DSB or Deutsche Bahn for Copenhagen, Hamburg.

• Deutsche Bahn for the German daytime section to Munich.

• ÖBB for the Munich, Innsbruck, Verona, Bologna corridor or the Hamburg, Innsbruck Nightjet.

• Trenitalia for an Italian backup connection from Verona to Bologna if your chosen train does not run through to Bologna.

For a trip this long, leave more transfer time than the minimum shown by a journey planner. DSB advises checking travel times before departure because track improvements in Denmark and Germany can change itineraries. ÖBB recommends booking the Italy, Austria, Germany Railjet and EuroCity trains early because of seasonal demand; advance sales open 180 days out.

Interrail and Eurail Passes Work, But Reservations Still Matter

Use an Interrail Global Pass if you live in Europe, or a Eurail Global Pass if you do not. A one-country pass is not enough because the journey crosses Denmark, Germany, Austria, and Italy.

Pass travel does not mean every train is reservation-free. Interrail lists the Hamburg, Copenhagen EuroCity Express/Railjet reservation as optional for most of the year, but required from 26 June until 31 August. The Munich, Verona, Bologna EuroCity Brenner/Railjet route carries an optional seat reservation, but a supplement is required when travelling to, from, or within Italy.

Night trains are different. If you use the Hamburg, Innsbruck Nightjet, book the seat, couchette, or sleeper place you want as soon as your plans are firm.

Stations to Search

Use the local station names when you search:

• København H or Copenhagen Central for departure.

• Hamburg Hbf for the first major transfer.

• München Hbf if you use the daytime route.

• Innsbruck Hbf if you use the Nightjet.

• Verona Porta Nuova if you change in northern Italy.

• Bologna Centrale for arrival.

Bologna Centrale is the station you want for the city centre and onward Italian high-speed trains. If your route planner offers a different Bologna station, check carefully before booking.

When This Train Trip Makes Sense

Copenhagen to Bologna by train makes most sense when it is part of a longer European rail trip, when you are using an Interrail or Eurail pass, or when you want the Brenner route through the Alps.

It is not a practical day trip. Plan an overnight stop or a Nightjet section, avoid tight last-train connections, and be especially careful in summer when Copenhagen, Hamburg reservations become compulsory for pass users and popular sleepers can sell out.
