What are trains for?
We have recently moved to within walking distance of a station from where trains to London take only an hour and ten minutes. My wife thought it would be a good idea to take our son to the Summer Exhibition before the school holidays, as he has an inset day at school.
The train will cost £27 each for an off-peak return and leave them a fair way off at Waterloo. That’s 54 quid if I’m not mistaken, to rattle up the track, and as long as you keep the trip short and don’t get caught in the rush hours.
To drive at leisure, with no time restrictions, will cost probably £12 in petrol, and £8 to £12 at the underground carpark in Sloane Street. They can walk or take a bus to Piccadily. That leaves enough for them both to have lunch within the price of the train, and come back whenever they like. We live by the A3 and driving takes maybe an hour and a half.
Public transport should never cost more than driving. Trains are hopeless.
