Karl Robinson joked that his side should catch the train to every away game in future as they finally lifted the Tuesday night curse.
The 2-1 win over Oldham was Dons first League 1 midweek victory of the season, and their first on the road since April 2013 when they beat Colchester 2-0.
Goals from George Baldock and Izale McLeod put Dons on their way, before former Don Charlie MacDonald started the Oldham fight back in the second half, pulling one back for the home side.
But after training late on Monday and travelling up the night before on the train, Robinson said it might become a habit if they win again.
“We got the train up, so I’ve told the chairman that’s what we’re doing now!” he said. “All the stats told you it’ be difficult for us tonight, but to a man, we were sensational.
“To come here, on a Tuesday night, with our record?!
Defensively, we were very good in the first half. But the fans certainly were loud in the second half.
“And we knew they’d come at us. I was disappointed to concede from a set piece, but the curse of the ex-striker goes on!
“But the way the players stood up to the challenge was a testament to them. Tactically, we got it right. I couldn’t be happier with the way we played.”
Baldock’s first goal in a Dons shirt came after just four minutes at Boundary Park, sparking huge celebrations for the popular 20-year-old.
And Robinson, who gave him his first start at Boundary Park in 2011, was delighted for him.
He said: “I’m made up for George. He took a terrible whack on Saturday, he was touch and go to play.
“I told him on Sunday that right back is his to keep now, and he said he’d be fit to play here. I’m so happy for him, he’s becoming a real favourite at the club.
“It’s hard living in the shadow of a brother who went for millions.
“But he’s standing on his own now, and that’s a huge credit to him. He really does deserve it.”
