I had the wisdom a while back to book a train journey passing through Birmingham for today. According to the nationalrail website, the first leg of my journey will be avoiding the station I want to get on at. I tried calling Virgin to ask them what to do instead, and they put me onto the rail enquiry "helpline" who said they didn't know that that train wasn't running and what I should do instead...
I've found in the past that if you phone a rail enquiry helpline more than once and ask the same question, you'll get different train times and fare prices.
