In Germany, the honest answer is that FlixBus usually wins on price and the train usually wins on time and comfort — but the gap between them varies enormously by route, and on some corridors FlixBus is genuinely the better all-round choice, not just the cheaper one. Here's how the two actually compare.
Cost: FlixBus wins clearly, most of the time
FlixBus's advance fares on popular German routes are typically well below Deutsche Bahn's (DB) equivalent advance fares, and the gap is usually largest on long routes between major cities — Berlin to Munich, for example, or Hamburg to Frankfurt. DB's pricing works on a similar advance-purchase logic to FlixBus (book early for the lowest "Sparpreis" fares, pay more closer to departure), so the price gap narrows if you're booking a DB Sparpreis fare well ahead versus a last-minute FlixBus ticket — but on a like-for-like advance booking, the bus is very often the cheaper option, sometimes substantially so on longer routes.
Where the gap narrows most is on shorter regional hops, where DB's regional tickets (and regional day passes covering multiple trips) can be competitive with or cheaper than a short FlixBus fare, especially if you're combining several short journeys in a day. Either way, comparing a fare in your own currency is easier with our currency converter if you're booking from outside the eurozone.
Time: the train wins on the direct, high-speed corridors
On routes served by DB's ICE (Intercity-Express) high-speed trains — the backbone connecting Germany's largest cities — the train is comfortably faster than the equivalent FlixBus journey, sometimes by several hours on a long corridor, since ICE trains run at up to around 300 km/h on the newest lines and make far fewer stops than a coach navigating city traffic and multiple pickup points. Berlin to Munich, for instance, takes roughly 4 hours by ICE against a considerably longer journey by coach.
On routes without direct high-speed rail — smaller cities, or connections that would require a train change and a longer overall DB journey — the time gap shrinks and can occasionally favour the bus, particularly where FlixBus runs a direct route that the train network only serves indirectly.
Comfort: broadly comparable, with real differences
FlixBus coaches are modern, with reclining seats, onboard WiFi (coverage can be patchy in rural stretches), a toilet, and usually a power socket per seat or pair of seats — a genuinely comfortable way to travel for journeys up to around 5–6 hours. Beyond that, most travellers start to feel the difference: a coach seat, however reclined, doesn't match the ability to walk around, visit a proper onboard café or restaurant car (on longer ICE routes), or simply stretch out that a train offers.
DB's ICE trains offer more space per seat, a quieter ride, a dining car or trolley service on many routes, and the freedom to move around the train — advantages that matter more the longer the journey gets. First-class DB tickets add extra space and quiet zones, at a price premium over both standard rail and FlixBus.
Reliability: DB's reputation has slipped, FlixBus has its own risks
Deutsche Bahn has, in recent years, developed a reputation for delays on some routes, driven by an ageing and heavily used rail infrastructure undergoing renovation in many areas — a genuine factor to weigh against its speed advantage on paper. FlixBus, running mostly on the Autobahn network, is exposed to road traffic and congestion instead, which creates its own, different delay risk, particularly around major cities at peak times or on long weekend travel days.
Neither is immune to delay; the practical takeaway is not to assume the train is automatically more reliable just because it's faster on a good day; check recent performance or reviews for your specific route if reliability matters more than speed for your trip, for example when timing a connection covered in our guide to minimum connection times.
Where FlixBus clearly wins
- Budget-conscious travel where a few extra hours in exchange for a meaningfully lower fare is a good trade — students, longer trips with many legs, or simply travellers prioritising cost.
- Routes without a direct high-speed rail link, where FlixBus's direct coach can beat a DB journey requiring a change and a longer overall trip.
- Last-minute travel, where FlixBus's walk-up fares are often still more reasonable than DB's near-departure pricing, which rises sharply close to the travel date.
Where the train clearly wins
- Long journeys between major cities on the high-speed network, where the time saving is large enough to be worth the extra cost.
- Journeys where comfort matters — working on the way, travelling with young children, or simply preferring more space.
- Booked well in advance, where a DB Sparpreis fare can match or beat FlixBus pricing while still keeping the train's time and comfort advantage.
Booking and practical differences
FlixBus tickets are bought through the FlixBus app or website, with a simple, flat luggage allowance — see our separate guide to FlixBus luggage rules for exactly what's included and what costs extra. DB tickets are bought via the DB app, DB Navigator, or at stations, with a somewhat more complex fare structure (flexible vs Sparpreis fares, and whether seat reservations are included or optional — reservations are optional on most ICE trains but recommended on busy routes and holiday periods, unlike some other European high-speed services where they're compulsory). If you're planning a longer trip through Germany and beyond by rail, our guide to Germany overland covers the wider network region by region.

Frequently asked questions
Is FlixBus always cheaper than the train in Germany?
Not always — a Deutsche Bahn Sparpreis fare booked well in advance can match or beat a FlixBus fare on the same route. On average and especially for last-minute bookings, FlixBus tends to be the cheaper option, but it's worth comparing both for your specific dates.
Does FlixBus have WiFi and power sockets?
Most FlixBus coaches offer both, though WiFi coverage can be inconsistent in rural stretches between cities, and power sockets are usually shared between adjacent seats rather than one per passenger.
Which is better for a journey with lots of luggage?
FlixBus includes a set free luggage allowance with clear extra-bag pricing beyond that; DB doesn't charge for luggage at all, which can make the train the simpler and cheaper choice if you're travelling with more bags than a typical FlixBus allowance covers.
Is the train always faster than FlixBus in Germany?
On routes served directly by ICE high-speed trains, yes, usually by a significant margin. On routes without a direct high-speed link, or where a DB journey needs a change, the time gap can shrink considerably or occasionally favour the bus.
