So far my month on the 8.42 from Surbiton reads Canc 14L 12L 5L 20L 14L 8L 10L 22L 12L 10L 14L 17L. The 8.48 is similar. The journey is only supposed to last 19m! When are you going to start delivering service instead of this rubbish! And properly compensate people for the inconvenience you put them to? And ultimately be accountable?
I think we should compromise. Howe about we start with asking them just to run trains every day for a month without any breaks of more than 30 minutes, and work up from there. Best to start with baby steps before asking them to do the difficult stuff!
