Apple Store at Grand Central closed until further notice due to power outage

A power outage at New York City's Grand Central Terminal has reportedly forced one of Apple's most heavily trafficked retail stores to be closed until further notice.

Grand Central Terminal officials announced Monday morning that all stores within the station are closed because of power issues. In addition, entrances to the terminal along Lexington Avenue have also been closed. No timeline for reopening was given.

The power outage was caused by a broken water pipe in the terminal, a Metropolitan Transportation Authority official revealed to Gothamist. The water leak apparently hit a transformer, sources told Pix11.

The power outage reportedly began around 9:30 a.m. and affected the lower levels of the terminal, with sporadic outages on the upper levels. As of 11 a.m., power was restored to the main lobby, though according to Grand Central officials, the stores remain closed.

Train schedules have not been affected by the outage, though some ticketing machines were said to be down. NBC producer Keith Feldman revealed on Twitter that passengers can buy tickets onboard trains without penalty while the issues are still being resolved.

An estimated 700,000 people pass through Grand Central Terminal every day. Apple's store is located right in the heart of the transportation hub.
