<P> After leaving Euston, some HS2 services are planned to connect with Crossrail (opening 2018) at Old Oak Common . </P> <P> TfL have considered proposals to modify the route options for the planned north--south Crossrail 2 line, so that the route could potentially incorporate a direct link between HS1 and HS2 . This could be achieved by routing Crossrail 2 via Euston and St Pancras stations, the termini for the two high - speed rail lines . However, it is thought that the introduction of both HS2 and Crossrail 2 at Euston will cause capacity problems due to the additional passenger demand . </P> <P> The Department for Transport initially estimated the cost to be £ 30 billion to be funded by the government with the Manchester Airport station locally funded . The Manchester airport station is to be separately funded by the airport and the wider region . Cost estimates have gradually risen since the first figures were released . The City of Liverpool, omitted from direct HS2 access, may add a third source of funding . In March 2016 the city offered £ 6 billion to fund a link from the city to the HS2 backbone 20 miles (32 kilometres) away . It has received some funding from the European Union's Connecting Europe Facility . </P> <P> The first 190 - kilometre (120 mi) section, from London to Birmingham, was originally costed at between £ 15.8 and £ 17.4 billion, and the entire Y - shaped 540 - kilometre (335 mi) network at £ 30 billion . </P>
