I'm not. The whole argument is about density and how in Japan they aren't afraid or too stuck up to have passengers en masse on the platform waiting for a train like a train station should rather than to wait like a plane. Whether it's shinkansen or rer or whatever is irrelevant. I'm not arguing for a mode of transport, just for more efficiency instead of old world via mentalities
Remind me if I am wrong because my experiences in Korea, Japan and China blend together sometimes.
In China the High Speed Rail experience is much more like an airport or airline - security checks to get into the station concourse (Once you have your ticket), you are then held in the concourse until your gate opens, then you can move to the platform level and wait for the train. Once boarded you have a specific car and seat and your ticket is checked to make sure you are in the correct seat. One major difference is size and scale, these stations are generally huge to immense in every facet, compared with North America, much more on the scale of airport terminals, and the crowds are also immense - line ups for tickets, for security, and the trains are full. The Chinese regional systems (the older railways) are very different - different stations, routes, tracks and speeds. Crowded , but in most other respects, more relaxed in terms of officialdom.
If I remember correctly, both Japan and Korea had similar systems in place for High Speed Trains, but just less officious and overdone. And then the slower speed regional systems which were again, pretty relaxed.
In all of these countries, the High Speed trains are large and the crowds similar - but the stations are built to handle these volumes. Platforms are 3 or 4 or 5 or 6 times the size of a Union platform, concourses on a scale similar to Pearson. You can argue that this is just overkill, and you would be probably right, until you travel during the Chinese New Year (for example) and the crowds are just so immense that these places are just jammed to a point where its hard to move around. Plus there is a lot of civic pride in these systems, they are a sign of cutting edge technology developed at 'home' and viewed as such, and government policy places a lot of emphasis on their performance and place in the national and regional economies. And development is continuous.
So much different then this country. But then again Canada is the 2nd largest country in land mass a with a population of 35 million? China is the 3 or 4th largest country by land mass with a population of 1.4 billion people. Japan is a country with about 3% of Canada's land mass and a population of 125 million or so, Korea has about 1% of the landmass and a population of 50 million. Size is not an excuse for VIA, they can and should be better in many ways, but there are differences that play a role in how they are funded and how they are run, and these will not go away easily.
Perhaps our comparisons should be with legacy stations in Europe? Again, Union would be smaller, but Union was built on those station models and when you compare handling people, maybe those comparison might be important and relevant?
