North Shields were denied a fifth successive league victory by a late equaliser from the Citizens on Tuesday evening.
It was a disjointed match due to two lengthy stoppages as the home lights went out, the first blackout coming just after Dan Wilson had fired the Robins into a 35th-minute lead and they were looking on course to add to their tally.
When play resumed, both Wilson and Gareth Bainbridge went close as the Shieldsmen looked to be by far the more positive outfit.
Before the hour mark, again the Durham pitch was plunged into darkness.
The hosts started to play more as the second period wore on, and Aiden Haley struck the bar, but Graham Fenton’s lads remained resolute and looked like holding on to their advantage.
Kevin Hughes had returned to skipper the side, and John Grey again slotted in at left back, while Chris Bannon took over the gloves from the injured Sean McCafferty.
Gary Ormston shone in the middle, but late substitute Ryan McGorrigan lasted only a few minutes before he was forced to hobble off after a bad challenge.
An 88th-minute Durham corner wasn’t cleared, leading to the leveller, but in the fourth minute of added time, Ben Richardson all but won it again for Shields, only to see his goal-bound effort somehow blocked on the line.
North Shields: Bannon, Donnison, Grey, McKeown, Hughes, Coppen, Ormston, Richardson, Bainbridge, Wilson (McGorrigan 83) (Walker 86), Holmes (Luccock 72). Subs (not used): Parker, Summerly.
On Saturday, North Shields are at Shildon, kicking off at 3pm, before entertaining Newcastle Benfield next Wednesday at 7.30pm.
