Signalling Design Engineer at Network Rail

What does a Signalling Design Engineer do?

As a signalling design engineer for Network Rail, who owns, operates and maintains the railway which train operating companies run their trains on, you’ll ensure the railway is safe by designing signalling systems. Signalling is incredibly important - it allows the trains to move safely on the network.

As a signalling design engineer you’ll be designing signalling systems for the railway. This could mean upgrading older signalling systems or designing brand-new ones for projects like HS2 and the Digital Railway. You’ll be flexing your design muscles by using CAD (computer-aided design), making sure that all the components and electrical circuits work and can be implemented on the railway.


Usually, you’ll work full-time, five days a week. However, you may find yourself travelling to meetings with stakeholders, so there’s plenty of variety in how and where you work. You’ll also visit railway sites to see your design being carried out in the right way (and suggest improvements if it isn’t).
