Performance and reliability

We work as part of an alliance with Network Rail to make our train services more reliable and run on time.

All our services are monitored every day, including Sundays and Bank Holidays.

The Public Performance Measure (PPM) is the standard measure for train service performance throughout Great Britain. There are two elements – punctuality and reliability.

  • Punctuality – the percentage of our trains that arrive at their final destination within five minutes of the advertised time. When a specially advertised revised timetable is in operation, at times of engineering work for example, we are measured against the revised times
  • Reliability – the percentage of our advertised train services that operate

We have targets for our PPM for the network as a whole, and for each region.

Service Quality Incentive Regime (SQUIRE)

We work with Transport Scotland to ensure we maintain the high standards of our stations and trains through the Service Quality Incentive Regime (SQUIRE).

All of our stations and trains are checked every four weeks, and any faults or areas for improvement are reported and repaired.

  • We check our stations to make sure lights are on when required, stations and shelters are clean and free from litter, and seats are safe to sit on
  • We check our trains to make sure seats are clean and safe, there's a comfortable ambient temperature and toilets are available for customer use
  • We work hard to ensure our stations and trains are free from graffiti
