Overview
The ICE 20 does something few European trains manage: it stitches together the flat, salt-tinged north of Germany with the folded, river-cut edges of the south, and it does it in a single unbroken run. Board at Hamburg Altona and you leave under the Elbe's grey light; step off at Basel Bad Bf and you're within reach of the Swiss border, the Rhine now narrow and fast rather than broad and industrial.
This is not a scenic tourist train dressed up for photographers. It's a proper long-distance InterCityExpress service, the kind Germans use to get to work, to weddings, to connections onward into Switzerland. That's exactly what makes it worth understanding properly: the reward here is in the sweep of the journey, not in any single showpiece view.
Because it's a long north-south artery, the ICE 20 rewards a bit of planning — where you sit, when you travel, what you expect from catering and comfort — more than a short regional hop would. This guide covers the practical shape of the trip using only what's confirmed about the service, and points you to DB Fernverkehr for anything time- or fare-specific.

The route: Hamburg to Basel, north to south across Germany
The ICE 20 runs the length of the country, from Hamburg Altona in the north down to Basel Bad Bf on the Swiss frontier. In practice this means the train crosses several distinct bands of German landscape in one sitting: the flat, wind-scoured plains and waterways around Hamburg give way, over the course of the journey, to more rolling, settled central German terrain, before the land begins to tighten and rise towards the Rhine corridor in the south.
By the time you're approaching Basel, the character has shifted again — the openness of the north is long gone, replaced by the denser, river-shaped geography of the upper Rhine borderlands. It's a journey that genuinely changes outside the window, which is unusual for a train primarily built for speed and connection rather than sightseeing.
Timetable and booking: always check with DB Fernverkehr
Because this is a long cross-country ICE service, timings and frequency can vary with the season and with wider timetable changes across the network. Rather than quote anything specific here, the honest advice is to treat the schedule as fluid and to check current departures directly with DB Fernverkehr before you plan anything around it.
The same goes for booking: DB Fernverkehr's own channels are the place to confirm availability, routing on the day, and any seasonal adjustments to the service. On a journey this long, it's worth booking with enough lead time to secure the class and seating you want, rather than turning up and hoping.
Fares and classes: what actually differs on board
As with timings, exact fares aren't something to guess at — DB Fernverkehr is the only reliable source for current pricing and any fare conditions attached to this service. What can be said in general terms is how the classes tend to differ physically on a train of this type.
First class typically means a quieter, more spacious carriage environment, with wider seating and more generous legroom, and often a greater sense of personal space at your table or window. Second class is the workhorse of the train — perfectly comfortable, well used, and where most passengers will naturally travel, with a livelier, more communal atmosphere. The core experience of watching Germany unfold outside the window is available to everyone on board; what changes between classes is comfort and space, not the view itself.
Which side to sit for the best of the scenery
Given the length and north-south orientation of this route, the landscape shifts enough that no single side of the train dominates the interesting views throughout. The sensible approach is to think in stages: the flatter, water-laced terrain near Hamburg suits window-gazing on either side, while as the train moves south and the land becomes more textured towards the Rhine and the Basel approach, a window seat becomes more rewarding generally, simply because the terrain itself has more relief and interest to offer.
If scenery matters to you more than a table or extra workspace, prioritise a window seat when booking through DB Fernverkehr, and expect the character of the outlook to change gradually rather than in one dramatic reveal.
Onboard experience: what travelling on the ICE 20 is actually like
This is a modern German long-distance train, and the onboard feel reflects that: panoramic windows that let you track the changing landscape properly, a steady, purposeful ride, and the general hum of a train built for covering serious distance in comfort rather than for short hops.
Catering on ICE services of this kind is typically available on board, giving you the option of a proper break for food or drink partway through a journey that spans a large part of the country. It suits settling in with a book, laptop, or simply watching Germany change shape outside — this is a train for travellers who enjoy the process of a long journey rather than just its endpoint.
Best season to travel
The character of this route changes noticeably across the year, given how far north to south it runs. In winter, the northern stretches near Hamburg can feel stark and low-lit, while the softer light and slower pace of the season further south towards Basel and the Rhine borderlands often feels quieter and more atmospheric.
In the warmer months, the longer daylight hours mean you'll actually see far more of the journey — useful on a route this long, where a chunk of an off-season trip could otherwise pass in darkness. Spring and early autumn tend to offer a reasonable balance: decent daylight without the peak crowds of high summer travel.
Alternatives and onward connections from Basel Bad Bf
Arriving into Basel Bad Bf puts you right at a genuine crossroads. From here, onward connections into Switzerland and further into the wider European network are readily available, making the ICE 20 a sensible spine for a longer multi-country trip rather than a there-and-back excursion.
If the full Hamburg-to-Basel run doesn't suit your plans, the route can just as easily be broken into shorter legs, joining or leaving the ICE 20 at intermediate points along its path through Germany. As ever, DB Fernverkehr's own booking tools are the place to check what onward or partial journeys are realistically available on any given day.
A little context
The ICE 20 sits within DB Fernverkehr's InterCityExpress network, the backbone of Germany's high-speed and long-distance rail travel. Services like this one grew out of a broader push, across the modern era of German rail, to connect major cities and regions with fast, comfortable trains rather than relying solely on older intercity or regional patterns.
Its Hamburg–Basel routing reflects a familiar logic in German long-distance planning: linking a major northern port city with the southern reaches of the country and the Swiss border, giving passengers a single-train option across a journey that would otherwise require several changes.
Common questions
- Can I check exact departure times for the ICE 20 online?
- Yes — timings vary by season and timetable changes, so always check current departures directly with DB Fernverkehr rather than relying on general guides.
- Is first class worth it on this route?
- It depends what you value. First class generally offers more space and a quieter carriage, while second class gives the same views and journey for a livelier, more communal ride. Confirm current fares with DB Fernverkehr before deciding.
- Which side of the train has the best views?
- There's no single best side for the whole journey, since the landscape changes considerably from north to south. A window seat becomes more rewarding as the train moves into the more varied terrain towards Basel.
- Is food available on board?
- Catering is typically available on ICE services of this kind, giving you the option to eat or drink during the journey rather than needing to bring everything with you.
- What's the best time of year to take this journey?
- Spring and early autumn tend to offer a good balance of daylight and comfort, though summer gives you the longest views along this lengthy north-south route. Winter travel further north can feel starkly beautiful but darker for longer stretches.
