Taken this morning by a friend of mine

I must admit to being surprised by the extent of the amber warning, especially the wording - I thought SW England was Devon and Cornwall, with most of the amber warning map showing up the West Country. I believe the main point of severe weather warnings though is to alert people to the risk, hence 'be prepared', rather than carry on with your day with no idea of the potential for bad weather.  Who does National Rail take their day to day forecast from anyway, public warnings come from the Met Office, but there are many firms out there selling forecasts to companies?

Thank you for the welcome! I thought the subject worth raising as it was only because of my knowledge of the railway that I perservered. Not sure how many of your average user would know of this ticket, and how best to obtain one.
The line was poor quality, the on hold music very scratchy, I found it very difficult to understand the person. I wondered at the time whether, like other call centres, outside normal working hours calls are handled abroad??

Partly my fault as i tried to buy from Honiton, but when I asked for Exeter St D I was given the same reply - FGW^▸ (First Great Western) don't operate that route. I had to explain that I wanted EXT to RDG^▸ (Rail Delivery Group, or Reading station, depending on context) then onward to GTW!! Several "hold please" later success!!
I read somewhere afterwards that after going through all the tedious, "press 1, press 9, press 47.5 etc" rigmarole, by pressing '2' to buy tickets I was re-directed to the trainline.co? If I'd asked for FGW customer services then I would get some-one with abit more route knowledge??  All in all 1 out of 10 for their phone system, but still please to get the ticket (^141 with no restrictions rather than ^180 off-peak) in the end!
