The public performance measure (PPM) measures the performance of individual trains advertised as passenger services against their planned timetable as agreed between the operator and Network Rail at 22:00 the night before. PPM is therefore the percentage of trains 'on time' compared to the total number of trains planned. A train is defined as on time if it arrives at the destination within five minutes (ie 4 minutes 59 seconds or less) of the planned arrival time for London and South East or regional services, or 10 minutes (ie 9 minutes 59 seconds or less) for long distance services. Where a train fails to run its entire planned route calling at all timetabled stations it will count as a PPM failure. ## Key features - Public Performance Measure (PPM) tracking - On-time train arrival definition - Service type punctuality thresholds - Failure count for incomplete routes - UK passenger train network data ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | No Ads | $1.99 | one-time | ## Frequently asked questions about UK Trains ### What is the Public Performance Measure (PPM) for UK Trains?
