Good Evening All,Woodford,This is somewhat outside my area of expertise, but since I was asked.............................
Thanks for your well thought out information that makes great technical sense. Top speed is not the only thing that effects total travel time. More often a lower top speed with less stop start and congestion though good planning and management allows for a significant reduction in total travel time.
What would be the effect of having South of Seymour double line bi-directional running for both over time and reliability due to not having crosses?
Also the effect on having a clear run though Melb. e.g. no delays at Dynon etc?
As always find your input quite interesting from a technical point.
Currently the VLine's service can be delayed by anything up to 20 minutes due to both cross's at various points and shunting activity in Dynon. The morning VLine service to Melbourne can get from Craigeburn to Southern Cross yard in 26 minutes, but this is quite rare from my experience. I do not know about current practice as I have not been down to Melbourne for some time (like WHO would travel by train with the current past performance of the Albury train) but in the past the controlers were definitely giving the pass's priority., but one does get a situation like the morning Melbourne bound service where it has to cross the north bound XPT, (usually at Passing Lane 2) so a pass then has to be delayed.
I cannot see this changing any time soon though, neither the state or federal mobs appear to have any real time for rail
Its quite instructive to look at ARTC's timetables of the NE liine, the time taken for VLine services between Southern Cross and Seymour vary quite widely depending on apparently how many cross's there are. The evening service to Melbourne taking a good deal of time due I assume to the number of night freights going north.
I've been a long time lurker on this thread being a North East resident but I thought you might appreciate this. On the evening up service I now have a beaut routine. At Avenel I ring the Railway Hotel at Seymour and order a Parmi. I get off at Seymour wonder over to the pub, eat, wonder back, get on the velocity BG service and usually beat the Albury train into Southern Cross. Technically I think the ticket states no break of journey but no one has pulled me up on this yet. It's a nightmare of trip on that single standard gauge line but a decent feed makes the trip quite enjoyable.
