Okay I'm the driver of one train and you're the driver of the other.

I see that your train is shorter then the double section of track and that  
you're travelling faster then I am, therefore you hit the double section  
before I do. But my train is still the same length as the double track (or  
longer), so although I can clear the section without hitting the end of  
your train (because you're shorter) I would expect you to hit the end of  
my train (because you're faster).

I mean I can it understand how it works from Darren's perspective sitting  
by the track, just not from the drivers.
