on Sunday night and Monday morning, we strongly recommend that passengers

particular, on Monday morning. Please check the website for updates on
travel conditions, or telephone National Rail Enquiries on 08457 484950'
FFS, there's barely a cm on snow so far and given their usual rubbish service my 35 minute train journey will take over an hour tomorrow morning.
