I was somewhat concerned to find that of all the machines at Worksop not a single 'assistance' button actually works leaving the station without a help point so far as I could find. There's a little notice on the machine telling you to call an 0800 number for assistance but without any info that you need to select customer relations to get any help if you're stranded - the obvious option for up to date train running info connects you to the entirely useless National Rail Enquiries instead. Also only any good if you happen to have a phone on you. Not at all good for a fairly large and part time staffed station. Happily I was able to assist and kick Northern into providing replacement transport before my back working departed as I was approached for help.
