Hi, we are moving to Petersfield in the summer, and my husband will be commuting to London. Can anyone let me know how busy the trains to London Waterloo are leaving between 6.30-7.30am during the week? Will my husband be guaranteed a seat? We are trying to work out how far from the station we can live, and if he can work on the train, it gives us more wiggle room with how far we go! Thank you!
