How Railly works

Live boards
The site asks National Rail for updates every minute. What you see is what they say — platform changes, cancellations, expected arrival times. I refresh on the server, so the timestamps are the ones I actually saw.
Door-side predictor
UK trains drive on the left, so on a side platform the doors open on the side away from the driver. The predictor looks at the platform layout (side, bay, or island) and the train's direction to tell you which side to stand on. It covers 433 platforms across 48 stations. Where I don't have data, it just doesn't say anything.
Delay-repay calculator
Operators use the same National Rail bands (15 / 30 / 60 minutes). The calculator finds the delayed or cancelled legs in your journey history and scores them against the operator's own scheme. You get a list of claimable journeys with a direct link to the right claim portal.
Reliability chip
The “X% on time · typically +Nm late” on each row is computed from my own data — how the same service pattern (operator, route, weekday/weekend, departure hour) has actually run over the past 30 days. It's not timetable data, it's what happened.
Data sources
Live trains: National Rail. Station facilities and accessibility: National Rail Knowledgebase, refreshed quarterly. Delay-repay rules: Office of Rail and Road standard thresholds, plus each operator's published scheme.
