I want to book a train that goes through London (PAD-EUS) when I search for fares the cheapest it gives me allows 45 minutes to get through London (lunchtime-ish) which doesn't seem all that long. If I ask for extra time it charges me a boatload more. If I book the fares separately it costs 30 pounds or so more (ACK!) but it doesn't make much of a difference which train I take to PAD so it is crazy the cheapest way only allows one particular train.
Why do they make this so difficult?
Also if I book the two legs separately does it mean I have to buy a tube ticket?
I'm middle aged and am traveling alone so apparently railcars are out unless I suddenly become a student in the next half hour.
