It's common practice of all operators to withdraw certain journeys that aren't profitable or indeed withdraw it completely if they are making a loss on it.
Few operators will use a service that makes shedloads of money (i.e. 21) to keep a service like one of the quieter "East Durham" services going. As any business does, GNE needs to maximise their profit levels - whether this is done at the expense of a few customers or none at all, it needs to be done.
