Chris, many thanks for the graphs / updates.
The cancellations, currently running at 1 train in 5, is the real shocker. With a service that only runs twice a day in each direction, timekeeping (even a 10 to 15 minute delay) isn't such a big problem unless a customer of the railways is looking to connect onwards into another service that's also infrequent.

I've updated the graphs again... a good start to the week but shadowed by cancellations on Thursday & Friday.
Just some pointers:
> I'm aiming to update the graphs every Friday
> Trains showing as No Report will not be counted, as I am unsure of whether they ran or not
December Raw Data:
A total of 42 trains were monitored.
33 of these ran (78.6% reliability).
6 of these were on time (18.2% on time).
24 out of 33 departed within 5 minutes late (72.7% punctuality).
Between 10th and 31st December, of trains which were monitored:
The 0644 service was cancelled 1 time
The 0717 service was cancelled 1 time
The 1908 service was cancelled 1 time
The 1950 service was cancelled 6 times
Total 9 Cancellations

Sorry for the slight delay, but I've now updated the graphs above.
Some pointers to sum up the week - normally I wouldn't post a new reply but just edit the post HOWEVER I have had to make the minimum value on the reliability graph LOWER AGAIN to an APPALLING 55% as reliability is currently standing at 58.3%.
This must be an all time low and is just not acceptable.
On a (slightly) brighter note, punctuality and the rate of on time trains of those trains which did decide to show up has gone up slightly.
How would services into London be if there was a reliability rate of just 58.3%?

Just updated the graphs... sorry for the almost 1 month gap... I'm pleased to announce that for February, reliabiliity is currently up at 96.3%  which is 26 out of the 27 trains I have monitored so far have run. Punctuality is better than January, however there have only been 4 trains out of 26 which were on time... January Raw Data: A total of 77 trains were monitored. 55 of these ran (71.4% reliability). 18 of these were on time (32.7% on time). 45 out of 55 departed within 5 minutes late (81.8% punctuality). Between 1st and 31st January, of trains which were monitored: The 0644 service was cancelled 6 times The 0717 service was cancelled 4 times The 1908 service was cancelled 4 times The 1950 service was cancelled 8 times Total 22 Cancellations Edit to Moderator(s) - would it be possible for this to be a sticky topic? Then it wouldn't dissappear? Just a thought... |

Sorry it has been so long since I've updated these graphs. This topic was a little dusty as I have been very busy, but I've found a few free moments and have updated them.
There ARE signs of IMPROVEMENT:
- only 1 cancellation throughout the whole of February
- Punctuality is gradually improving
- There are more on time trains than ever since the new timetable started
- Nearly 1 in 2 trains are on time so far in March, compared with under 1 in 5 back in December
Does anyone agree with me?
February Raw Data:
A total of 70 trains were monitored.
69 of these ran (98.6% reliability).
17 of these were on time (24.6% on time).
55 out of 70 departed within 5 minutes late (79.7% punctuality).
Between 1st and 28th February, of trains which were monitored:
The 0644 service was cancelled 1 time
The 0717 service was cancelled 0 times
The 1908 service was cancelled 0 times
The 1950 service was cancelled 0 times
Total 1 Cancellation

Sorry for the lack of updates for the last month... I have (as ever) been busy and am trying to fit things in. Have also had a virus which has decided to delete a lot of lets say, big things. I've cleared it now though and thankfully my internet hasn't been deleted (yet), so will update the graphs and statistics for March within the next few days - if my PC is still alive that is...
