Game 4 is in Washington on Monday (8 p.m. ET; NBC, CBC, SN, TVAS).
"We figured it might be tough to get to the game (driving)," Oshie said Sunday. "Some of the guys said it was actually the fastest they've ever gotten there, but we decided to take the train if there was going to be traffic just to make it easy on us."
Although Niskanen and Oshie might not need to purchase SmarTrip frequent-user cards anytime soon, they seemed to enjoy riding among the fans to the Capitals' first home game in a Stanley Cup Final since 1998.
Oshie, who is in his third season with the Capitals, said Niskanen, playing his fourth season in Washington, is the more experienced Metro rider among the two.
"[Niskanen] has done it a couple more times than me," he said. "That was actually my first one to the game."
Niskanen didn't want to give away the details of their trip, but said they can take the Orange or Silver Line from Virginia.
"There's a stop somewhat near our house," Niskanen said.
They had to get off at the Metro Center station and transfer to the Red Line before taking that one stop to the Gallery Place-Chinatown station, where Capital One Arena is located. The closer Oshie and Niskanen got to the arena, the more red-clad Capitals fans boarded.
