Arriving London King's Cross from Doncaster at around 01:05 on a Friday night. Planning to take the Victoria Line to Oxford Circus and change to the Central Line to West Acton. Anything to worry about in terms of personal safety?
Only once you reach West Acton! Up to the point where you exit the system, it's fine; as others have said, still a fair number of decent folk around using the system; the odd lairy inebriate at times, but you can usually hear them a mile off.
