I simply don’t agree with the conclusion though I appreciate the approach to thinking about products.
I recently chose to take the train vs driving and the factors behind that decision were:
* Time, yes. Train was approximately the same but an actually a bit slower.
* Cost. Train was slightly cheaper when looking at the true cost of driving. Also significantly cheaper than flying.
* Experience. This is entirely overlooked in the timetable centric approach. Train is simply the most pleasant way to travel long distances (maybe ferry is competitive there). I was able to move around and get work done and enjoy the view. If the train company had swapped my train for a bus I would NOT have been a satisfied customer.
* City center to city center (vs airport to airport). Had the train company said “we swapped the arrival location to the airport but technically we still got you to the city” I would NOT have been a happy customer.
The “trains as timetables” hypothesis would imply that the train could meet my needs via something other than rail travel and would definitely lose me as a customer.
On the other hand, improvements such as better wifi service (it was terrible and not sure why cell service is also poor on a train) or a route that was more scenic but did not impact my arrival time significantly would positively affect my likelihood of choosing train.
So the better lesson is know your customer needs and know their specific jobs to be done and center your hypothesis around this.
I think a lot of that is colored by the fact that you were doing a long-distance trip. I would completely agree with your points if I were, say, living in Frankfurt and planning a holiday in Paris.
But the math is a lot different for regular day-to-day trips, and for that I do think the timetable is the primary product. My goal is to get from A to B, and do so 1) reliably, 2) quickly, and 3) affordably. I don't really care if this means taking the car, the bus, the underground, the train, my bicycle, or a ferry - I'll use whatever option is most convenient.
If I'm only in/on there for 30 minutes, I could not care less for a scenic view. It matters far more whether there is a frequent service I can rely on, which doesn't involve half a dozen needless busy-work with transfers and endless waiting and anxiety for each connecting service. The more it acts like a taxi, the happier I am.
