HS2 is a high-speed railway project that aims to connect several major cities in the UK, including Manchester, and reduce travel times between them. The Manchester leg of the HS2 railway line will have a station located in the city center, which is expected to boost economic growth and create job opportunities in the region. However, the project has experienced significant delays. (generated by ChatGPT)

The first part was due for extension between 2030 and 2034 to help boost transport in the north of England, but the window has now shifted to 2032 to 2036 while services will not extend to Manchester until the 2040s. (quote from Sky)

Note that question is phrased to allow lines that are no longer described as HS2 to resolve YES

'High-speed' is here arbitrarily defined as trains travelling over 250km/h (to capture the difference between current fast rail in the UK and planned/operational high-speed rail, ie HS1 and HS2 phase 1. Notice that by this definition domestic services on HS1 are not high-speed)
