Derbyshire County Council has admitted that a software issue means that £340,000 worth of bus information signs may never work.
The boards, which advise when buses are due, were bought three years ago, but 35 remain in storage and eight have not been switched on.
After the purchase bus operator Trent Barton told the council the software used for the signs was “unreliable”.
The council has been unable to find better replacement software.
The Conservative-run authority said it was still trying to resolve the issue – along with an additional problem affecting 25 of its other bus information signs which have been out of order for several months.
It said it could not rule out that both sets of signs would never work again.
What a complete waste of money.Follow @pdview
