Duke the Dog2 "Under the current timetable.....are not able to achieve the necessary acceleration in the short distance between Green Park and Reading Station"
Of course the timetable can only change if you change the type of train on the line, what a load of b*ll*x. This man has no idea what he's talking about.
In many instances it is possible to open a new station without having to change the type of train being used.
In this instance the journey time from Reading to Basingstoke with 3 intermediate stops is about 25 minutes, which allows 5 minutes for the train to unload and reload at the end of the line before returning, giving a regular-interval service every 30 minutes.
So in this specific case, adding an stop at Green Park would bust the timetable if you rely on using the existing diesel trains.
Electric trains accelerate more quickly, so the time loss caused by the Green Park stop can be recouped by the faster acceleration from each of the intermediate stops, thus still maintaining the 25 minutes end-to-end journey time.
