But ebay????? Sounds like a major cut back. If people now know the bits and bobs they were selling on ebay had the potential to mess up hundreds of thousands of commuters journeys they could have a field day. Forget internet hacking and viruses you could just sell spare parts of the tube at sky high prices.
A dot matrix indicator is currently going for about �180 and I assuming that it's the components that the Tube are after rather than the sign itself, otherwise we might be seeing - "Sale Now On" or "Half Price Bargains" rather than the usual "Ealing Bdwy - 13 mins"
