Let's get moving with the affordable medium-speed alternatives to the old dream of high-speed rail

More than half a century has passed since high-speed rail (HSR) effectively began operating, in Japan in 1964, and it has been mooted for Australia since 1984. I estimate that the cost of all HSR studies by the private and public sectors in Australia exceeds $125 million, in today's dollars. But the federal government is now less interested in high-speed rail (now defined as electric trains operating on steel rails at maximum speeds of above 250km per hour), and instead favours "faster rail" or medium-speed rail.
