Speed was something which drove the construction of the world's first inter-city railway, the Liverpool and Manchester line. Business people could travel from one place to the other for a meeting, and then return the SAME DAY.
I have a branch which went into the railways early, and moved around.
Thomas Dunbabin was born in 1818 at Sutton Weaver in Cheshire. By 1841 he was an Engine Tenter (fireman) at Derby, headquarters of the Midland Railway.
His first child was born at Brentwood in Essex in 1843. Brentwood at this time was the temporary terminus of the Eastern Counties Railway, which later became part of the Great Eastern. The following year he was back in Derby. He then returned to East Anglia, re-marrying in Wisbech following the death of his first wife. By 1851 he was settled in King's Lynn, Norfolk, where he died in 1894.
His brother George also went engine driving. In 1851 he was at Burton on Trent. He is recorded at Fenton in Stoke-on-Trent, Lowestoft in Sufflok, Orpington, Canterbury and Sydenham (all in Kent), Fulham in Middlesex, Olney in Buckinghamshire, and ended up at Sharpness Docks on the Severn estuary, where he died in 1897.
One of my great grandfathers was born in Lancaster, his birth being registered on 8 Mar 1871. By the census, the family are in Barrow in Furness, too far to walk but straightforward by train. His father died in Ulverston; his mother died 38 years later back in Lancaster. Several families I've researched also appear to "commute" along the north side of Morecambe Bay.
If there was work, there was a train to get you there.
