Firstminute Train Journey?

Question

I am getting a train from London Paddington to Bristol Temple Meade at the end of July and I was wondering whats the difference between the classes A to E?

I am thinking of booking a £10 ticket, but I know you get what you pay for so was wondering what each class is like?

Thanks if you can help

Answer 1

with train journeys Advanced tickets are sold so cheap so they can get "bums on seats"  an expensive ticket will be for travel on a busier train while a cheaper ticket in your case a £10 will be for travel on a quieter train so go for the £10 option as on trains you its better to get a cheap ticket where your guaranteed a seat rather than turning up on the day buying an expensive ticket and your guaranteed nowt
