In a freakishly uncanny twist of fate on what is already a freakishly uncanny similarity between Melbourne & Toronto - our primary airports are roughly the same distance from the central areas (and even in broadly the same direction from aforementioned areas!) - last week we saw commitment at the state level to finally commit to building a rail link.
It was somewhere in the range of $500mil to $1bil in capital to build the necessary infrastructure for the UPX, no?
They're budgeting $8-13bil for Melbourne's Airport Rail Link (MARL)! The Federal Government out of the blue in the May budget said they'll stump up $5bil and now the state government has been prodded enough and come to the table and said they'll match funding.
Last week's announcement 'put to bed' the debate on the route from central Melbourne to the airport (surprise surprise it's a route which has been favoured by governments for 20+ years) however the pricetag is baffling for a few reasons.
The Melbourne Metro Tunnel project is about linking east and west lines and bringing a metro/subway-like service to the inner city by ramping up frequencies on suburban services - to the east two branches combine about 30k out of the city and about 10k to the west, at present, there's only a single branch - but that will become two soon.
Adding an airport line, technically, is quite easy by adding a third western branch (like the spur built for UPX comes off a GO corridor now) but population is growing so fast that there's already warnings that there won't be enough space on the metro tunnel track pair to cope with outer suburban growth as well as more complexity (a third western branch).
As part of the upgrades + tunnel project, from Sunshine (which is key to the airport line) to Dandenong [which is an equivalent distance of Mississauga/Pearson to Scarborough via central Toronto] a new CBTC signalling system will allow trains to run every 2 min (the new trains to exclusively operate east west can fit 1100 people in 7 cars, works to extend them to 10 cars are seen as a second phase capacity add-on for a later stage will likely push train capacity to 1500 or more) but because trains do the heavy lifting from outer suburbs and inner areas and the very high pop growth the track pair will be saturated quickly. If airport trains were a branch of this track pair, from the city they'd have to stop all stations so as not to compromise overall line capacity.
Conversely, there's a concept out there which addresses another rail issue we have: separation of metropolitan and regional services called the AirTrain (highly recommend flicking through
this conceptual brochure) which is a nutshell is about building a new track pair from the city to the airport and a second phase would divert two regional lines away from existing metro lines - therefore increasing capacity/services across both regional and metropolitan areas.
It has a lot of tunneling and a back-of-the-envelope costing would put it within $8-13bil.
We don't know if that's whats on the cards but will by next year -
as the route's been settled, now the focus is on the specific business case for the line on the now-settled route - and if it's anything like AirTrain, we'll have a dedicated fleet for the shuttles between the airport and city but also likely we'll have next gen regional trains that can run under wires (with pantos) or diesel (or maybe hydrogen in 10 years?) outside the metro area.
AirTrain concept aims to have a train every 10 minutes and a journey time of 15 minutes (made possible because the route will be built for the faster regional services as well (benchmark: 160kph).
It really is freakish when comparing Pearson to Toronto and Tullamarine to Melbourne - as I said earlier, roughly the same distance away and same direction.
The Bloor and Weston stops on the UPX line are like Footscray and Sunshine on the Melbourne route - Footscray (Bloor) in our case won't have an airport stop (but they'll be connected via the high frequency new metro line that will start operating cross-town in 2025 - Metro tunnel project) but Sunshine (Weston) has some major
planning work to concentrate employment and residential development out there. The Victorian government are now referring to the 'Sunshine super-hub'.
Anyhow - sorry for taking over the thread, but yeah, lots of similarities on what's happening in either hemisphere at the moment. Just wish we had politicians with more balls who'd create cross-town links like the Eglington LRT here.
