An app allows you to buy and redeem tickets for trains on a smartphone.
The service is a way to save time on a train journey and help you get on and off the train faster.
The app, called trainx, is available on Android, iOS and Windows phones and is available in some cities, including Sydney, Melbourne and Brisbane.
But it has not been available in South Australia since last November.
The trainx app, which is being rolled out in South Australian and New South Wales, will offer passengers the ability to book trains using their mobile phone number and the QR code they scan when boarding the train.
You can then book tickets with the app.
If you do not have an iPhone, you can book tickets on an app such as SeatPass.
However, if you do have an Android smartphone, you may need to use the QR Code on the mobile app.
You will be asked to enter the correct address for the train and if you enter a wrong address, the train will not start.
The platform The platform at the Rocky Railway Station in Adelaide.
Picture: Andrew Meares It is unclear how long the service will be available, but passengers who use the app can buy and use trains on the platform and transfer their tickets.
There is a queue line outside the platform.
You are required to get off the platform before the next train arrives.
Once on the train, you will have the option to transfer your tickets and wait for another train to arrive.
However if you are travelling from the CBD to the South Australian CBD, it is likely you will need to get on at the Sydney Airport.
Train tickets can also be bought from the station on the railway.
The station is open from 8am to 9pm every day, but only for train ticket purchases.
The stations are a lot smaller and the stations are closed on weekends and public holidays.
The Rocky is a popular stop for many trains to the Gold Coast and it is located on the northern shore of the Brisbane River.
If a train is arriving at the station and you want to transfer, you would need to go to the Rock, Rock and then Rock, but you do still need to buy tickets.
It is also a popular destination for tourists and some locals.
It would be a good idea to take your mobile phone to the station to buy your tickets.
Trainx has been rolled out to a few other cities.
Melbourne, Sydney and Brisbane are all rolling out the service in the coming weeks.
The mobile app is being used in more than a dozen cities in Australia, but not in South America, the Middle East or South Africa.
But, there are plans to roll it out in the United States.
In the United Kingdom, the service has been rolling out to stations and hotels in a number of cities.
TrainX is available to download from Google Play, Apple App Store and other app stores.
If the app is not available in your location, you could buy a ticket using the app in a store.
It will cost you $7.50 per ticket.
It can also save you time on your trip.
