For many people in Kent, Sussex and Essex, the train is the only way of getting about - especially if they work in London.
So today's news about big fare rises in January 2013 means they will either have to pay up - or find a new job.
At the moment a Brighton to London season ticket costs £3392 - that will increase by more than two hundred pounds.
Ashford to London on the high speed line goes up from £5504 to 5845. While Sevenoaks to London from 2980 to 3164. Dover to London - using the high speed line - increases from £5556 to not much short of six thousand pounds.
Today's announcement sees a 6.2% average increase in rail fares from the start of next year.
Rail commuters in the western part of the Meridian region already pay anything between £3,400 to get to London from Brighton. And up to £7,500 a year to travel to the capital from Wiltshire.
From 2013, train passengers from Bournemouth will pay more than £6,100 a year for an annual ticket. If you live in Swindon, you'll have to fork out almost eight thousand pounds a year.
John Denham, Labour MP for Southampton Itchen, has expressed alarm at today's news regarding rail fare increases.
Mr Denham said:
"Living costs are rising and hard-working families are finding it hard to make ends meet. For many the daily commute is now their biggest household bill.
"It’s time for the Tory-led Government to do something to help Southampton’s many commuters.
“Those already spending over £4,000 on a season ticket from Southampton Central to London are likely to be hit hard by these increases if they go ahead.
"Quite simply, the Tory-led Government should not be increasing fares using its current formula, which puts fares at 3% above inflation. It is far too high. Train companies should not be allowed to increase ticket prices by any more than one per cent above inflation across all routes.”
The retail prices index figure for July, which is used to determine how much regulated rail fares are allowed to increase in 2013, rose to 3.2% from 2.8%. Some tickets can go up by a further five percentage points - or more than 11% - as long as they are balanced by cuts on other fares.
Rail fares will rise by on average 6.2% from January - that's three times the average pay rise.
