There are only offical (guiness world record) records for London and New York, however tubeforum.co.uk/forum have a list of records on other networks that their membera have unoffically competed in.
Wonder what the route was for the Tyne and Wear Metro? Main problem is the fact you need to double back so often.
Aye, just depends on if they used other forms of transport as well. With one bus and one rail move I could probably do it in around 3 hours.
Technically speaking isn't the Shields Ferry part of the Mertro. It does appear on the maps after all. Or is this purely from an interchange point of view?
It's certainly been done on the T&W.
