How long is the train travel from London to Manchester?

Approximately. Thanks alot!

about 7 carrigges

3 hrs roughly. The timetable says 2hrs 25mins but bearing in mind weather and whatever allow another half hr.

Fastest train: 2 hours 10 minutes.

There are 3 trains per hour from London Euston to Manchester Piccadilly operated by Virgin Trains; most take about 2 hours 10 minutes. For the lowest fares book as far in advance as possible via their website www.virgintrains.co.uk or by visiting the ticket office at Euston Station

Sometimes five carriages othes seven each one about 70 feet
So a total length of 350 feet or 490 feet.
But if you must make a journey of it put it another way 2.5 hours.
