Question to those who know about freight diagrams, in particular the lines they travel on where the route has both slow and fast lines. I usually note the following where there are 4 tracks (unless exception ofcourse):
WCML - Freight travels on the slow lines (on the right hand side lines in the direction of going north)
ECML - Freight travels on the slow lines (on the outer lines which lie either side of the centre fast lines)
Great Eastern - Freight travels on the fast lines (which are initially on the left then switch to right hand side going East)
MML - Freight travels on the slow lines (on the right hand side lines in the direction going north)
Great Western - Freight travels on the slow lines (on the right side lines in the direction going west)
South Western Main line - Not sure about this one, I think its the fast lines?
South Eastern Main line - Again not sure, maybe the fast ones?
Southern main line?
I guess the question is (at least for the first five, why do they travel on the fast lines for some and slow lines for the others?
