There's a massive car park at Walton Hall Park Leisure Centre, the proposed site of this new stadium - I've parked my car there for the last 15 years and walk from there to Goodison. The road itself is a straight run from there to the Showcase and the East Lancs Road, and on to the M57. It's easier to get away from there than it is from Goodison.
There was talk of re-opening the Walton & Anfield Railway station on the Canada Dock Branch line. The line is still active but used for goods trains. It would be situated opposite the Taxi Club. Existing Platform foundation still in place 150mts long. 5 mins walk to stadium. Next to local Police Station (less chance of vandalism). Exits onto Walton Lane dual carriage way.
It would be viable given Anfield will be 60000 capacity and the proposed new stadium 50000. That's an extra 30000 people travelling to games.
If they reopened the line, this is how it would be routed. You'd be able to get a train from the city centre, from Bootle, and from all the current places, such as Sandhills and Kirkdale. It would be ideal:
