Lee Johnson’s side scored two goals in seven minutes midway through the first half, the first an own goal from Railwaymen defender Terell Thomas before Ross Stewart grabbed his eighth of the season.
Stewart added another early in the second half before substitute Leon Dajaku netted a stunning fourth on the counter-attack to seal an impressive win for Johnson’s men.
The Black Cats return to Wearside this weekend for the first time in a month when they welcome Charlton Athletic to the Stadium of Light looking to regain top spot in League One.
The Addicks are on a poor run of just one win in eight games as pressure begins to mount on manager Nigel Adkins.
But before that, we take a look at what’s been happening around League One over the last 24 hours.

1. Cowley ashamed of defeat
Portsmouth boss Danny Cowley did not shy away from the pressure he finds himself under at Fratton Park after Pompey were thrashed by former boss Paul Cook’s Ipswich Town last night to leave them 17th in the League One table some seven points adrift of the play-off places. The former Lincoln City manager pulled no punches in his assessment to Hampshire Live. “[It was] unacceptable. I feel ashamed really and ultimately, I take full responsibility for it. Every single person within our group has the responsibility of going away, of looking at themselves and seeing what they can do to give more to this team. They [the fans] love their football, they are proud of their football club and they are proud of their city and we as a football club are letting them down and it is really hard for me to stand here and say that.” (Photo by Jacques Feeney/Getty Images) Photo: Jacques Feeney
2. Scowen happy with Wycombe progress
Former Sunderland midfielder Josh Scowen is pleased with the start his Wycombe Wanderers side have made to the League One season. The Chairboys ground out a solid point at promotion rivals Rotherham United last night as Gareth Ainsworth’s men look for an immediate return to the Championship. And Scowen, who was a product of the club’s academy, is happy with life at Adams Park. "We're happy with the four points [from the last two games]. Obviously, it would have been nice to get six, but to go back home now with that under our belts, going into Saturday now I'd say we're in a good place. Being in the Championship last season, we’ve got some real quality players here. It’s come a long way since I started out here, and it’s been a pleasure to return and see how much we’ve come on. There are some really good teams in this league this year, so we have to be on our game all the time." (Photo by Pete Norton/Getty Images) Photo: Pete Norton
3. McLaughlin return boosts Cod Army
Ex-Black Cats defender Conor McLaughlin made his return to football last month after finding a new club following his exit from the Stadium of Light in the summer. The Northern Irishman linked back up with his old club Fleetwood Town and has had a positive influence in the dressing room according to boss Simon Grayson who told The Gazette: “He’s been here before, knows what it is all about and is an experienced player. He knows the football club, is versatile, can play right-back, centre-back and in the midfield. He feels at home here and he’s a great lad to have around the dressing room with his experience.” (Photo by Pete Norton/Getty Images) Photo: Pete Norton
4. Robins midfielder loaned out
Cheltenham Town midfielder Elliott Bonds has joined Kidderminster Harriers on-loan. The 21-year-old is heading to the National League North side to build on his match sharpness after a serious injury ruled him out for the majority of last season. The Guyana international joined Michael Duff’s side in the summer after spending time with the club on-loan from Hull City last season. Bonds loan deal is set to run until early December.
