Apologies but I've not rrad all 5 pages.
If some TOCs advised passengers not to travel and others don't offer this advice, does that mean they expect the weather to be worse overall for those TOCs advising people not to travel?
For example Southern, Thameslink, Greater Northern, Gatwick Express, Southeastern, Grand Central, London North Eastern Railway, amongst other are advicing customers not to travel, according to National Rail Enquiries but South Western Railway and Greater Anglia, to name but two are not advising this.
