Searching for a Train Number in DB Navigator: Finding a Train by Its Number

Updated: August 2026 – You want to search for a train number, but the journey search stubbornly insists on a start and destination. This guide shows you where the actual train search is in DB Navigator (Deutsche Bahn’s journey planner app), which input formats work reliably, how to read a complete route from the result – and what to do if the search finds nothing despite the correct number.

Can you search for a train directly by its number?

Yes – there’s a separate search function next to the journey search for this. It draws on the same journey information from Deutsche Bahn AG as the journey search and therefore knows exactly the trains that are in the public timetable. While the journey search expects a start, destination and time, the train search only asks for a train designation and a date. As a result, you don’t get a connection, but the route of the train: all stops in order, the scheduled times and – for current trains – platform details and delay notices.

Depending on the app version and interface, the entry point has different names, such as Zug, Zugsuche or Zuginformation (train, train search, train information). Look in the menu for an item that asks for a train designation instead of two places – that’s the right one. For spotters, this function is far more valuable than the journey search, because it shows the train as a whole rather than just the part between two stations. How to follow a number you’ve found live afterwards is described in the guide to tracking DB train numbers.

Which input formats work

The most common problem isn’t a fault in the search but an unhelpful entry. This overview sorts out the common variants.

Input variant	Likelihood of a result	Why
Product code, space, digits	Very high	The clearest form; the search recognises category and number separately
Just the digits	Medium to high	Often works, but gives several suggestions from different product groups
Code and number written together	Low to medium	Depending on the interface, not recognised as a category
Line number instead of train number	Low	The line doesn’t denote a single train
Number with the wrong date	Zero	The train doesn’t run on that day
Vehicle number instead of train number	Zero	Vehicle numbers don’t appear in timetable information

If you’re unsure about the number itself, the guide to where the train number is shown on the train and at the station will help. And what the ranges of digits reveal about product and route is explained in the article on decoding train numbers for ICE, IC, RE and RB.

Step by step: finding a train by its number

Zero results: the three typical cases

If the search comes up with nothing, it’s almost always down to one of these three situations. Work through them in this order.

Case 1: wrong day of operation

The train exists but doesn’t run on the date selected. First check whether you’ve accidentally left today’s date set although you’re looking for a train from yesterday. Then try a typical weekday – if you find the number there, the date was the cause.

Case 2: format or category doesn’t fit

Without a product code, the sequence of digits remains ambiguous; with the wrong code, it leads nowhere. Enter the number again with a space between category and digits. If you’re not sure of the code, first try just the digits and choose from the list of suggestions.

Case 3: the train isn’t in the public timetable

Freight, transfer moves, light engine movements, engineering trains and many special workings don’t appear in passenger journey planners. Here the search isn’t broken, it’s simply not the right tool. For freight, the guide to following freight trains live will help, and for local services it’s also worth looking at how to find live departures from regional transport associations.

From route to spot planning

The real benefit of the number search isn’t the result, but what comes afterwards. The route is a complete timeline of the journey – and with a little thought, a timeline becomes a plan.

Turning stops into time windows

Take the two stops between which your chosen spot lies and look at the difference. This span is your search window. If the spot is roughly in the middle, halve the span roughly – but always round up, not down. The timetable already contains recovery time that a train doesn’t necessarily need, and it doesn’t contain signal stops that it may get after all. If you plan too tightly, you’ll regularly lose trains.

Thinking about direction and light

The route also tells you the direction of travel at your spot, and that determines the effect of the picture. A train coming towards you needs a different viewpoint from one moving away. Combine the direction with the position of the sun at the planned time before you set off – that takes two minutes and stops you ending up photographing into the light.

Stacking several trains

Once you’ve found a train, it’s worth looking at what comes shortly before and after it. If you’re standing at a spot anyway, you can take in extra trains with almost no extra effort. Simply search for the numbers of the neighbouring trains and note them down too. That turns a single train into a session that’s worthwhile.

Don’t forget the way back

The route ends somewhere, your day doesn’t. Check straight away how you’ll get away from your spot again, especially for evening trains on branch lines. The last train back is part of the planning – and it’s the reason why, with tight connections, you’re better off taking in one train fewer.

If you don’t know the number at all

The reverse case is at least as common for spotters: you’ve seen a train pass, but have no number. Then you work via time and place. The exact time and the section of line give you a few candidates in the normal journey search, which you then narrow down further by vehicle type and train length. The complete process is described in the guide on how to reconstruct a train journey afterwards.

If you’d rather work entirely without installing anything, you’ll find the options in the article on tracking trains without an app directly in the browser. And if you’re less interested in the individual train than in the overview, the comparison of the best train radar tools and maps will help.

What to bear in mind with the number search

• Always note the number and date together. A train number without a day of operation doesn’t denote a specific train and can’t be reproduced later.
• Don’t accept suggestions blindly. With several results, the category decides. A glance at the starting station prevents you choosing the wrong train.
• Stops aren’t passing times. Between two stops, you have to estimate yourself – and add a generous buffer.
• Real-time data only appears shortly before the journey. For dates searched far in advance, you only see scheduled times, no forecast. How scheduled and actual times differ is explained in the overview of live tracking of trains and buses.
• Safety before timing. Your photo position is fixed before you plan the time. Track areas, platform edges beyond the marking and operational railway land are off limits – no timetable changes that.
• Not every train can be found. If a number simply won’t produce anything, check whether it belongs to the public timetable at all before searching further.

Verdict

Searching for a train number isn’t a hidden secret function, but a separate type of search next to the journey search – you just have to know it exists. Three things matter: product code plus number as the format, the right date, and the willingness to go through the three typical causes one by one when you get zero results. After that, you have the complete route and with it the basis for any spot planning.
