. Started as an independent venture in 2005, the project changed hands several times before being acquired by Brightline, who had recently begun their initial Florida route. Construction is expected to start in 2020 with service to commence in 2024. In September 2010, Amtrak unveiled proposals for trains to run between Washington, D.C. and Boston, stopping at various cities along the way, including Baltimore, Philadelphia, and New York. The end-to-end journey time would be three hours. The proposals would cost $117 billion and would take 25 years to complete. Amtrak estimates that the capacity would be needed, as, even after current investment programs, the Acela trains will be full by 2030. The proposal envisages completion by 2040. North American High Speed Rail Group is seeking to build a privately financed high speed rail line between Rochester and Minneapolis-St. Paul. The line is expected to cost $4.2 billion to build. The eventual goal is to extend high-speed rail service to Chicago. Oceania Australia There have been several proposals to develop a HSR line between Sydney and Canberra (via SYD airport and CBR airport) to link the two cities and to provide an effective second airport for Sydney. The line is also proposed to eventually continue on to Melbourne (also possibly via MEL airport). It is worth noting that the SYD-MEL air traffic corridor is one of the busiest in the world, HSR would allow for journey times city center to city center quicker than flights plus associated procedures and travel. In September 2010, Infrastructure Partnership Australia (IPA) and AECOM proposed an east coast very fast train corridor from the Sunshine Coast and Brisbane (Queensland) and onto Sydney (N.S.W), Canberra (A.C.T.) and through to Melbourne (Victoria). East Coast High Capacity Infrastructure Corridors In May 2022, a leaked government document showed a draft for building a 250 km/h rail network around Sydney-Wollongong-Newcastle over the coming decades: Parramatta and Newcastle would have travel times slashed from 2.5 hours down to 1 hour, and Parramatta-Gosford trips would take 25 minutes. Parramatta to Canberra would take 90 minutes. New Zealand As part of ongoing studies to increase the speed of a rail service from Auckland to Hamilton, potential for a new standard gauge line was identified at a cost of NZ$14.425 billion; with trains travelling at 250 km/h and taking 69 minutes to travel between the two cities.
