Thameslink, which essence is to set up automatic train traffic through the center of London every 2.5 minutes, will not be completed until the end of this decade. Recall, the cost of the project is £7.5 billion, and this is one of the reasons for the delay. Many residents and guests of the city have been waiting for several years for the renovation of London Bridge and the adjacent railways, which will allow to provide more rapid train traffic.
However, from May 2018 the capacity of this hub will be increased to 35 thousand passengers during peak hours. Although people will not see the promised 24 trains per hour until the end of next year. At best, this design capacity will be achieved by the end of December 2019. As the National Audit Office reported, the government requires GTR to offer options to reduce the risk of breaks in the railway transport.
And, as follows of the above, the refusal to implement the Thameslink project quickly is one of such measures, because, as the authors of the document stress, "the Thameslink program is currently incapable of reliable and uninterruptable monitoring a more extensive network of railways."
