This is excellent and informative work. And, to be honest, the value of Eurotrib -- I doubt that I would have ever considered / seen anything about this without this community. And, I value that. Thank you.
A question ... taking it to today ... How does the explosion of information technology and reduced price for it change the value/approach of tiered/zone pricing? It makes it far easier to play with timed prices and be far more specific in terms of those prices without overburdening the train / railroad employees while maximizing (potentially revenue) while likely confusing (at least some) riders.

Actually, a more annoying aspect of time-pricing (early seats cheaper than later one) is beginning a transaction at a certain price, only to find that by the time you are ready to pay, the seat isn't available anymore at that price... Un roi sans divertissement est un homme plein de misères
