Hi,
I am a student current studying in Sheffield and I am looking for some clarification on some figures.
My issue is with the figures that state Merseyrail is frequently among the top performing operators for punctuality in the country.
http://www.networkrail.co.uk/about/performance/
http://www.liverpoolecho.co.uk/news/...ompany-3347168
http://www.passengertransport.co.uk/...tuality-claim/
My two questions are;
Can someone explain the difference between RTP and PPM, mentioned in the third link.
RTP = Right Time Performance (percentage of trains arriving early or
within 59 seconds of schedule) over year to December 8, 2012.
PPM = Public Performance Measure over year to December 8, 2012.
And if there many be factors which push these figures up to such a high standard, such as train cancellations not being included.
I am originally from Merseyside and based on personal experience, recently viewed twitter pages such as #Merseyfail and #MiseryRail, I am very sceptical of these figures.
Any help would be brilliant but anything that is sourced, especially by Journals or credible newspapers would be more useful.
Thanks
