As the Caps chase their first Stanley Cup, Metro will mark a historic occasion of its own Thursday: It will remain open an extra hour– for an away game — thanks to Monumental Sports and Entertainment.

The Caps’ owner will pay $100,000 to keep the system open until 12:30 a.m. the transit agency announced Wednesday night, as the team tries to wrap up the NHL championship in Las Vegas, where they face off against the Golden Knights at 8 p.m. EST.

The extra late-night service will accommodate fans attending a viewing party at Capital One Arena, along with festivities outdoors, along with others out watching the action at parties around the District, Metro said. Gallery Place, Metro Center and Judiciary Square stations will remain open to riders after the system’s regular closing time of 11:30 p.m. Other stations will be “exit only,” Metro said.

“We are grateful that Monumental has stepped in to support the Caps, Metro and – most importantly – the fans,” Metro General Manager Paul J. Wiedefeld said in a statement. “I’m proud to say we’re in full ‘ALL CAPS’ mode at Metro, ready to do our part to provide great service before and after the game.”

Last train times were available on Metro’s website. (link:
