One of your assumptions states "absolute track circuit block section". I assume that "track circuit block" is meant, as absolute block is something different.
On the second graph on page 5, I think the x-axis is actually depicting time and the y-axis distance. In this case, the line for the stopping train should be below the non-stopping train. They certainly should not converge in the way shown. The figures seem to be right, it's just that the graph needs to be redrawn to make it clear what the figures actually mean.
The sentence "After 189 secs we can pass the fast passenger train" is possibly ambiguous. Does it mean that a fast train can be run 189 seconds after the stopping one? I would possibly reword to avoid the possibility that it means that the two trains should pass one another (which looks like it might be happening based on the graph).
