system in the same way as you travel on Sydney's suburban trains, trams, ferries and buses. If you don't have an Opal card, you can use your credit card to tap on at the station before you board your train and tap off after you arrive at your destination. Just look for the brightly coloured Opal validators or entry gates at the entrance and exit to each station. If you do not touch on before boarding your train you may be fined for travelling without a ticket.
If you do not touch off at your destination you may be charged more than you need to pay.
To travel on Long Distance (Regional) trains and Regional long distance buses you MUST buy your ticket and book your seat in advance. No matter how short your journey, if your train travels to or from Brisbane, Casino, Grafton, Armidale, Tamworth, Dubbo, Broken Hill, Canberra, Griffith or Melbourne then you MUST book your ticket and reserve your seat in advance. If you are travelling just a short distance on a Regional train (eg Sydney to Broadmeadow or Sydney to Goulburn) you might find that bookings are open for trains only one week in advance so as to permit longer distance travellers the chance to book seats first.
