With the UK’s big cities typically suffering from chronic underinvestment in infrastructure, the last thing that they need is rail strikes. The enduring actions by Aslef and the RMT on the Southern Rail network have severely damaged the capital. Every day of strike is thought to cost the economy £20m. The fragility of the network also raises questions for the commuter hotspots, and more generally for London’s competitiveness. The average commuter into London travels almost 40 miles / 75 mins – much more than other UK cities (UK average 45 mins), but the incentive is clear in terms of the central London wage premium. However, with more and more people being priced out of London and into commuting, continuing disruption to rail services may result in some looking elsewhere.
