01 · What it does

A probability on every connection we track.

For every connection Trainator covers, you get a single calibrated number — how likely the whole trip actually works end-to-end. One reading per connection, sitting quietly next to the result.

Per transfer and end-to-end

Each individual transfer gets its own probability, and the trip as a whole gets a combined score — so you can see both where the risk sits and how the journey looks overall.

Color-coded at a glance

Green, amber, red. The score is sized and tinted so the riskier transfers stand out without you having to read every number.

Reads the page, not you

Only the trip details visible on the page are used to compute the score. No cookies, no browsing history, no profile.

Constantly reworked

The model keeps learning. Every new trip in the wild feeds back into calibration, so the score you see this month is sharper than the one we showed last month.

02 · Reading the score

Three statuses. Three colors.

The percentage is the model's calibrated probability that the connection works end-to-end — you board the first train, you catch the transfer, and you arrive at the destination station no later than the schedule plus your acceptable margin.

03 · How it works

Three things happen when the page loads.

01 · LOOK

Reads the connection

When your search results or trip details appear, Trainator notices each connection on the page — which trains, which transfer station, how long you have between them.

02 · THINK

Predicts with machine learning

Trainator runs the connection through a machine-learning model trained on a broad range of operational data — not just past performance — to predict how this specific trip is likely to play out.

03 · SHOW

Draws the score in place

The badge slides in next to the connection. Toggle the extension off and the badges vanish — the host page itself is never modified.

04 · Supported scope

ICE connections on bahn.de — for now.

v1.0 focuses on what we can predict well: ICE departures, and any connection that starts with or follows an ICE. Other train classes, other operators and other booking sites are next on the roadmap.

It only wakes up when you're on a bahn.de search page or trip-details view, and stays out of the way everywhere else.
