What is considered as the true route of the Great Western main line? I know it starts from Paddington and goes to Reading, but what about afterwards? Is it the line through Newbury, Pewsey and Bradford-on-Avon or is it the line through Chippenham and Box tunnel, or through Chipping Sodbury tunnel?
What are the respective line speeds?
