All Monday to Saturday services are included in these calculations, except former First Great Western Link services. For those, we include Monday to Friday services. And we only include morning and evening peak services in the punctuality calculation. Peak services are the trains that arrive at London Paddington from 07:00 – 10:00 and trains that leave London Paddington from 16:00 – 19:00. We don’t include Sundays and public holidays in these calculations.
