Continuing on from the discussion in this thread
, it was announced today that $660 million
will be spent over the next two years upgrading the Pakenham and Cranbourne lines.
This is very curious, given that myself and other posters had been informed that the power and signalling upgrades were being undertaken as part of the skyrail project. The government is either re-announcing the same funding, or this is an entirely new project. Can anyone shed light on this?
According to the press release 13 stations will have their platforms lengthened to accomodate the new HCMTs, in addition to the 5 stations being rebuilt as part of skyrail. Unfortunately it does not say how long the platforms will be nor which 13 stations are getting the upgrade. The only clue as to length is that the new trains will be "20% longer" than current ones.
By my maths, that would put the new trains at just under 170m in length, which would be too long for pretty much every existing platform. Given that not all station platforms are going to be lengthened, I conclude that the 20% longer figure must include the intermediate cabs. Thus the HCMTs will be about 160m long.
This is really just a short term upgrade then, since Melbourne Metro will be built with 220m platforms.
The other interesting announcement is that "a section of track in South Dandenong will be duplicated." It doesn't say anything about an extra platform at Dandenong, so I'd guess that the existing Bombarder siding will be upgraded to duplicate the Cranbourne line as far as the stormwater drain between Greens road and Abbotts road.
