Wi-Fi on board

Keeping you connected

a drawing of a wi-fi logoWe have free on train Wi-Fi available on our trains – you’ll see the blue “Wi-Fi” signage on the door as you board.

You can connect to the wireless network in a few simple steps:

  1. Select 'southern_wifi' from your list of networks
  2. Open your browser and click 'connect'
  3. You're in!

Terms and conditions apply.

Access and coverage

If you have any issues getting onto the Wi-Fi, check that the train you’re on has a blue ‘Wi-Fi’ sticker on the doors. If you’re on one of our Southern diesel trains, we sometimes switch off the engines at terminal stations if it’s going to be there for a while. The Wi-Fi should activate when the engines are restarted. If you’re still having problems, please get in touch.

We use more than one mobile operator for the connection, so you should get reasonable coverage across most areas of our network, however it can be slower in the more rural areas. Tunnels and deep cuttings do vary with some having coverage throughout and some not having any at all.

You won’t see the on-train Wi-Fi drop out at these times, but the internet connection may be unavailable for a short while.


You will get 50MB allowance per day per device. If you reach this limit, you’ll still be able to connect but it will be at a slower speed. To ensure everyone on the train gets a good quality connection we do control individual download speeds.

There are a limited number of websites blocked, these are generally ones that are either inappropriate or data-intensive (such as video streaming or large files) to try and ensure everyone on the train can get a good quality connection.


Whilst we work closely with our supplier to keep the system secure, we do recommend you take the same precautions as you would do when using any public Wi-Fi. Find out more.
