DelayBahn provides historic punctuality data for German train travellers

A new, free online tool called DelayBahn is now open to anyone planning a trip on Germany’s rail network. Developed as a side project by Shashank Tripathi, the service does not attempt to predict future disruptions. Instead, it aggregates how trains have performed over the previous week, fortnight or month, giving users a realistic picture of which services are habitually on time.

How the service works

Travelers input departure and arrival stations, the intended travel date and a preferred time, much like any conventional journey planner. For each suggested itinerary the platform displays average delay figures, a risk rating for missed connections and an estimate of transfer reliability. Users can apply filters to prioritise the fewest delays, the lowest connection risk, the cheapest fare or the simplest route.

Data are available for the past seven, fifteen or thirty days, and detailed statistics can be examined for individual services. The site also flags passenger compensation rights under EU rail passenger regulations, enabling users to check whether a previous journey might qualify for a refund.

"How late is this train usually? Is there a more reliable alternative? Is that 7‑minute transfer actually realistic?"

Why it matters to rail users

By making historical punctuality information publicly accessible, DelayBahn gives commuters and occasional travellers a way to avoid costly missed connections and to plan important trips with greater confidence. The transparency of chronic delay data could also pressure train operators to improve reliability, as under‑performance becomes harder to ignore.

Although the platform operates independently of the state‑owned rail operator, Tripathi hopes it will evolve from a personal frustration remedy into a widely used resource for anyone relying on German trains.
