T4 and SCO post NIF and T3 Metro conversion

  simstrain Chief Commissioner

I'm not arguing for anything Totoro. The only way to achieve Transtopics goals is to build huge amounts of new infrastructure. ATO will not achieve a significant increase in trains per hour and it certainly won't allow 160km/h running in the Sydney network. Transtopic is basing all his ideas of a report in to running faster trains to Wollongong from 2014. The report was really just an election stunt for the 2015 election.

I'm with you Totoro that Metro will be the way forward in Sydney. Metro is modern with level boarding to help with loading times and is 100% accessible. It could easily be built to relieve the stress on the existing network allowing the ST network to become more of an outer suburban network.

115km/h minimum trains speed and running to the quality of the perway is bull dust DJF. The Sydney train's network is the most inspected perway in the country and is maintained to a much higher standard then the crap the XPT runs on outside of the ST network and miles ahead of anything in Victoria and yet 130km/h and 160km/h are allowed on those goat tracks. The speed is maintained because of the multiple stopping patterns on the ST network and the alignments. Nothing to do with the trains minimum speed whatsoever.

There is one aspect of our signalling system I do not properly understand.  

1) How far behind a train are signals at STOP?  Is it just the block the train occupies?  Or is it also the preceding block?

2) What is the correct terminology for the various states of the signals?  Stop, Caution, Caution Ahead, Clear ?  Or something else?

R/R - Stop
G/R - Caution
G/Y - Medium
G/Y Pulsating - Preliminary Medium (introduced about 10 years ago).
G/G - Clear.

Drivers may call these differently.

Something more recent and more relevant to the topic this time. From January 2020

The More Trains, More Services Program (the Program) is about building a modern and up to date rail system that will play its part in making Sydney a more productive and liveable city. The Program is a NSW Government initiative to simplify and modernise Sydney’s existing heavy rail network. While the Program will eventually deliver benefits to the entire network, TfNSW propose to start by targeting improvements on Sydney’s busiest lines. The first lines to benefit from the program will be the T4 Eastern Suburbs and Illawarra Line, the South Coast Line and the T8 Airport and South Line. The Program is central to delivering the NSW Government’s long-term vision and commitment to the state’s transport and infrastructure needs. The Program proposes to increase the total number of peak services on the T4 Eastern Suburbs and Illawarra Line by approximately 30 percent and providing a more comfortable journey for customers in the Sutherland Shire, Illawarra and South Coast. Under the More Trains, More Services Program, an additional 29 Tangara trains will be introduced to the T4 Eastern Suburbs and Illawarra Line and potentially the South Coast Line, subject to further development of the operational requirements of the network.

With the 17 additional B-Sets which I remember were ordered for Sector 3, it makes sense. The OSCars could also cover for those Tangara sets to allow for “growth” of services of sector 3. How many Tangara sets are currently rostered to run T4 and SCO services on weekdays?

See that’s the really interesting part. A big infrastructure spend may yet be possible, and has even been hinted at by State and Federal Govt, as part of COVID recovery plans.

So to me the speculation is not about whether it’s possible (with significant track straightening and driverless operation, I’m sure 160km/hr would be *possible*). The speculation is about how much money Govt will cough up for Sydney Trains; i.e. what is committed and what is not.
