restricted to due to the length of track and its topology. Proposed maglev systems Many maglev systems have been proposed in North America, Asia and Europe. Many are in the early planning stages or were explicitly rejected. Australia Sydney-Illawarra A maglev route was proposed between Sydney and Wollongong. The proposal came to prominence in the mid-1990s. The Sydney–Wollongong commuter corridor is the largest in Australia, with upwards of 20,000 people commuting each day. Current trains use the Illawarra line, between the cliff face of the Illawarra escarpment and the Pacific Ocean, with travel times about 2 hours. The proposal would cut travel times to 20 minutes. Melbourne In late 2008, a proposal was put forward to the Government of Victoria to build a privately funded and operated maglev line to service the Greater Melbourne metropolitan area in response to the Eddington Transport Report that did not investigate above-ground transport options. The maglev would service a population of over 4 million and the proposal was costed at A$8 billion. However, despite road congestion and Australia's highest roadspace per capita, the government dismissed the proposal in favour of road expansion including an A$8.5 billion road tunnel, $6 billion extension of the Eastlink to the Western Ring Road and a $700 million Frankston Bypass. Canada Toronto Zoo: Edmonton-based Magnovate has proposed a new ride and transportation system at the Toronto Zoo reviving the Toronto Zoo Domain Ride system, which was closed following two severe accidents in 1994. The Zoo's board unanimously approved the proposal on 29 November 2018. The company will construct and operate the $25 million system on the former route of the Domain Ride (known locally as the Monorail, despite not being considered one) at zero cost to the Zoo and operate it for 15 years, splitting the profits with the Zoo. The ride will serve a single-directional loop around Zoo grounds, serving five stations and likely replacing the current Zoomobile tour tram service. Planned to be operational by 2022 at the earliest, this will become the first commercially operating maglev system in North America should it be approved. China Beijing – Guangzhou line A maglev test line linking Xianning in Hubei Province and Changsha in Hunan Province will start construction in 2020. The test line is about in length and might be part of Beijing – Guangzhou maglev in long-term planning. In 2021, the Guangdong government proposed a Maglev line
