Re: Basel tram system
Without having any personal experience but just looking at the table, it all looks quite logical.
The more zones required to travel within, the greater the time allowance for the ticket;
e.g. To travel in and through 4 zones, a 240min time allowance is given (which appears to be the max. for anything over 3 zones up to 8; but obviously the price increases as the number of zones do).
The ticket should be purchased related to the number of different zones required for travel, then the applicable time limit for that number of zones, applies.
