So yesterday i took the metro in Newcastle to get to the mainline station to get a connection to edinburgh. However i only had notes in wallet and although with a full intention of buying a ticket i couldnt as the metro only has coin operated ticket machines. i was also travelling at 9.15 in the morning thereofre no shops were open where i could have got change from. subsequently while travelling ont he metro i was asked to show a ticket, obviously i couldnt and was given a £20 penalty notice. this also caused me to miss my connection and fork out £40 for new tickets even though we had set off with loads of time to spare and i got the feeling the attendant was being particularly slow on purpose causing me to miss my train. what are my chance of appeal against the fine and getting any sort of compensation? many thanks
