ION - Waterloo Region's Light Rail Transit

[plam]

While the majority of systems are like that, Hiroshima had a second staff member aboard it's tram system, and you paid your fair when exiting at their station (board all doors, exit 1 door).

In Stockholm (or was it Göteborg?), the fare attendant on board walked up and down, looking for new passengers. You'd then pay them and they'd use a machine to issue you a ticket.

I just wanted to point out that it's not uncommon or limited to third-world applications to have onboard fare collection/verification.

I suppose it happens from time to time, but it still seems hard to pay for this additional staff member in most places and so I would say that it is fairly uncommon to have a person collecting fares on-board.

In Switzerland there are only 3 lines where you don't have to buy your fare ahead of time, the 3 touristic lines which cost way more than everything else. (I tried to find the trains below S-class trains here: https://www.sbb.ch/en/timetable/timetabl...mbols.html but could not find them on any schedule). Of course, staff is probably the most expensive in Switzerland than anywhere else. In general, Switzerland is on a proof-of-payment system.

While most trams in Amsterdam require you to use a farecard or ticket machine, some along the tourist routes actually have a collector in a little booth; they both sell tickets and give directions and assistance.

Yep, tourist routes are the ones that it seems to me can afford on-board ticketing.
