City's joy at double swoop.
The Heiniger brothers, Carl and Richard, have signed for a Durham side still looking for its first point of a traumatic season.
Wide man Carl Heiniger played in the FA Cup first round for Team Bath several years ago after being part of the Newcastle United Academy. Goalkeeper Richard was briefly on Bristol Rovers' books and has played abroad, as well as for Whitby Town in the UniBond League.
Manager Lee Collings said: "It was important to strengthen the squad, so it is good to get two new faces on board, and ones with a decent pedigree.
"Richard has been out of the game for a while but could make his debut tonight, while Carl, who has been at Morpeth Town, faces a fitness test on an ankle injury."
Halifax, led by Gateshead-born manager Neil Aspin, have won 10 and drawn two of their 13 UniBond First Division North games.
However, a poor second-half performance saw The Shaymen crash out of the FA Trophy 3-1 at Guiseley at the weekend.
"The League Cup won't be a priority for Halifax, who are a big club at this level, with a large fan base and a sizeable budget," added Collings.
"Hopefully they'll have one eye on their league game at Woodley Sports on Saturday although they'll want to bounce back from the disappointing defeat at Guiseley. "It is another tough game in a difficult season, but we had a productive training session at the weekend and the lads look up for it."
