I'm presuming that my character would leave from Euston on the London to Birmingham line, and then would change at other points, possibly via the Grand Junction to the Manchester and Liverpool Railway, and then from Manchester to Leeds and then to York.
Allowing for changes, etc, is this journey more likely to have taken two or three days or longer? I assume that either Manchester or Leeds would be likely break points. I'm also assuming that there were no alternative eastern routes rather than the north-west and then north-east journey described here.
