As someone who works on the Thameslink Programme and the wider industry, can I ask why all the focus on Real Time Trains ''uploads'? The May 2018 timetable isn't established in its final draft until 14/03/18?
I'm surprised someone would ask that, let alone here! But in answer:
These are changes that have been subject to both quite a lot of hype and quite of a lot of well publicised information, some of which has later turned out to be misleading. Even the sort of members of the general travelling public that aren't on this forum are really curious about what's going to happen. In Cambridge we were expecting up to 4 new trains an hour from May (2 starting from Cambridge North), and these had been subject of a lot of press releases to the local paper over a long period of time. There's been publicity (sought by TL) at every key stage in the physical works in London, the expansion of Cambridge station, at every stage of the platform extensions more locally, and every stage in the progress of the train contract from signing to delivery, and at every stage of the consultations.
In recent times this has reached a crescendo as many key stages are being reached really frequently. We've had the consultations go out very widely, and aspects of them (like dropping the service to Cambridge North) have been really contentious and lead to MP complaints / local protests. We've had the saga of the platform extensions. We've had the complaints about the seats that have a) made national and local papers and b) increased awareness of the service changes. We've had the well publicised announcement of the wider delay in issuing timetables. We've had the preview train services start with journalists invited onto the first one (advertised in the press as if this was the beginning of a usable direct service to Gatwick).
... So people really want to know what these... 2/4 trains an hour, I mean 4 trains an hour but only from Cambridge, I mean 2, I mean 1? What? 1 a day??? 1 an hour? From when? Services with the nice new trains, I mean awful trains? with more seats? less seats? more capacity? what? Running from stations with longer platforms? Some stations with longer platforms? Some stations with some platforms longer? What? ... are going to be like.
