 Included in the report are draft timings which put Birmingham less than an hour from London, Manchester just over an hour, Liverpool just under 90 minutes, and just over two hours to Glasgow and Edinburgh, with sixteen trains per hour estimated from London, and four trains per hour between the regional cities.The report also looked into the question of services to Heathrow Airport, and came to the conclusion that running all trains from London via Heathrow reduced the benefit of the line by as much as £3 billion.Instead, Network Rail's proposal would entail a short spur from the main line terminating at Heathrow, reducing the road and air traffic to the airport from the cities that the line would serve.
