I don't understand train pricing.
If I go to the Trainline site, it costs me £70.10 one way to London.
Cost £70.10 for a return.
Or if I get a Super Saver, it is £121.30.
Now I am not sure if that is 70 quid each way, I think it is.
If I take the early train, just before 5 AM, it is £147.60 one way.
I will say that the prices have dropped since I last took the train up about 4 years ago.
Megabus cost me £15 one way, but they no longer run a service. National Express do and it is £34.40 one way.
