Like every type of industry the rail network needs to think about being energy efficient and using new, more sustainable types of power. Dan and Bex investigate…

Trains can travel faster and more efficiently if they’re electric – but how do you electrify the network?  And why can it take time to do so?

Although the digital railway of the future will help make the best use of the networks we have, it’s likely that new lines will also need to be built.  Bex and Dan find out more.

We can get more trains running on the tracks by helping each one to go faster.  Bex and Dan find out how this can be achieved.

To make the best use of our existing rail networks, we need to get more trains running on the tracks – and one way of doing this is getting trains to run closer together.

Dan and Bex are thinking about the different users of the rail network – passenger, freight and maintenance trains.  All of which need enough space to do their job.

From moving trains and lighting carriages to making sure we can charge our phones, the railways need power.  But the kind of power used by the railways has changed over the years.  Bex and Dan find out more.
