Why does the Ingleburn end have a bit of overhead near the junction, is it a legacy of the old loop?
If the whole idea it was for for a freight line one way or another, why was the overbridge not designed to allow double stacking ?
One peak arvo I was going home and waiting at Glenfield in the Via Granville Train which was in the dock platform, and then noticed an intermodal going thru on the main (cant remeber up or down) the NR loop was empty. It was peak (~3-4PM) and cityrail trains were constantly coming and going in addition to the via Granville in the dock.
Why send a freight on the main line if the loop was empty and the main were 'busy' already ?
The small piece of OHW on the loop is a leftover from the old loop.
ARTC are planning clearances for 10' 6" containers on standard height flat waggons. Double stacking is a long way off.
Because there are more conflicts and slower crossovers in the Down direction compared to the up, the G-I loop is more useful and more used in the Up direction. An up move on the loop, can also occur at the same time that a Down Glenfield terminator arrives in platform 1.
The loop appears to be able to hold two 1500m long trains, not that this happens often.
The loop would be more useful if it were long, but that is all that the original One Nation funding allowed.
