The grand old stations you mention are built to such a scale that the traveller has to look from a good distance to grasp their architectural merit. Given their respective neighborhoods, I doubt the average train rider takes the time to notice them

Some of the features which make a memorable station, in my eyes:
- it has to be a dead-end station, not a through station
- vast single overhead area for all trains are preferred
- flagship trains leaving for major destinations; I do like the mix of high-end trains from Europe's many railways at stations such as Milano.

Not to say the above features are the most functional.

I'll give a special mention to Buenos Aires majestic but desolate station (mostly local trains these days), and another to the well-executed, very modern Kyoto central station.

Nothing too special here in Switzerland.
