In the Southern Region we have some of the busiest and most complex railway infrastructure in the world.
Passenger numbers have doubled in the last twenty years while train services are mostly running on the same rail space and infrastructure as before. Today’s passenger services also run more frequently and over more hours of the day, seven days a week which causes more wear and severely limits the amount of maintenance time we have available to keep things running smoothly.
Much of our network was originally built in the 1800s and some of the track layouts, the ground engineering technology, the electrical supply and the station designs are perhaps not of the standard we would do things today.
Wherever we can, we are increasing the use of smart technology to squeeze the maximum capacity out of the railway space we have. Unfortunately, the historical nature of our infrastructure does affect the reliability of the network and impacts passenger and freight services.
We have many variables to contend with across the railway network including things such as extreme weather, electrical faults and track failures through to criminal damage and trespass. Below are three common issues we face at this time of year. Check back at other times and these will switch to the issues of the season or the moment. You can find out more, in our dedicated delays explained section.
