The public rail network of the region is largely split into two sections. These sections are centred around the two main west-east railway lines transversing the region, as there are currently no north-south railway lines wholly in the region. This is largely due to the mountainous regions of Snowdonia resting between the two lines, and low passenger numbers of north-south lines leading to their closure. The public rail network is managed and maintained by Network Rail. Historically, the region had a more extensive rail network with more interconnectivity of the current lines and more connections to the south. However, due to falling passenger numbers, the emergence of automobiles and other factors, the region's railways came under review, resulting in the Beeching cuts to the network. Many former rail corridors of the once more extensive network were superseded by road infrastructure. The numerous heritage railways scattered across the region serve as a reminder of the former railways across the region.
