How you pay for a journey, and the card that holds it

There is a settled way of talking about paying for transport. It is worth asking how much of it survives contact with the detail.

The card itself

The standard arrangement is a thin reusable card bought once at a machine and then loaded with whatever you need. The card carries a small charge of its own, and it is valid for a period, so keeping it between visits can be worthwhile. It is not personalised, so there is no registration and nothing to set up beyond buying it and loading it.

Machines at stations sell and load them, and they offer several languages, which removes most of the friction. Losing it means losing whatever was loaded on it, because there is no account behind it to recover from.

Two ways to load it

You can load a period pass, which allows unlimited travel for a defined time, or a cash balance drawn down per journey. These two modes generally cannot sit on the same card at the same time, which is the source of nearly all the confusion.

Switching from one mode to the other usually requires waiting until the existing one expires or is exhausted. For a short visit with several journeys a day, a period pass is usually simpler and often cheaper. For occasional journeys spread across a longer stay, a balance is the more flexible option.

Why one card cannot cover two people

Validation systems generally expect one card per traveller per journey, so passing a card back is not a workable strategy. That means a couple or a family needs one card each, and the small card charge applies to each of them.

This surprises people used to systems where a single contactless card can be tapped several times for a group. It also means buying cards for everyone on arrival is part of the arrival process rather than an afterthought. Rules on this do change, so confirming at a machine or an information desk on the day is sensible.

What the card covers

The card generally works across metro, buses, trams, the vertical lifts and funiculars, and suburban trains within the region. River crossings and some regional services may operate on different arrangements, which is worth checking before relying on it.

Zones apply on suburban rail, so a journey out to the coast or the hills costs more than a journey within the city. Validating on boarding is required even where nobody appears to be checking, and inspections do happen.

A valid card that was not validated is treated as no ticket at all, which is the most common way people are fined.

Buying tickets on board

Single fares bought from a driver or on board are typically several times the card rate for the same journey. That premium exists to push people onto cards and to speed up boarding, and it is not aimed at visitors specifically. It does mean that a visitor who never buys a card pays a substantial and entirely avoidable markup all week.

Carrying small change helps if you do end up buying on board, since large notes are often refused. The five minutes spent buying a card at the airport or the first station repays itself within two journeys.

Getting it wrong gracefully

If a machine rejects a card or a gate does not open, staff at station offices resolve this routinely and without fuss. Machines occasionally take payment without completing a load, and keeping the receipt makes that trivially fixable. Balances and pass expiry can usually be checked at any machine, which is worth doing before a day of travel.

Put simply, if you are unsure whether your card is loaded for what you are about to do, checking costs seconds and avoids a fine. None of this is complicated once, and it is genuinely confusing the first time, which is the honest summary.

The takeaway

Buy a card each, pick one mode, and validate every single time.

Pick the one that costs you least, and let the rest wait.
