 Possibly a better option and not that expensive would be to make the West
Line dual gauge, after all the points at Brooklyn and Newport are already
dual gauge, (except for the intermediate ones). One of the major flaws in
the SG out of Melbourne is the lack of crossing capacity, once a train
departs Manor  nothing can depart Tottenham Loop, if the West line was
dualed it would at least allow a train to cross at Newport.

As for the staff being booked off at Brooklyn and Newport, a proceedure
already exists for the crew of PM5 (9712) to obtain a staff for the
Newport - Brooklyn section from a staff box at Newport box  when Newport Box
is unmanned. (Sundays I think). Of cause CTC would solve this problem
completely.
