The Massachusetts Department of Transportation has received $41 million in federal funds to replace signaling infrastructure at Boston's South Station so trains run on time.
The Boston Globe reports the U.S. Department of Transportation funds will go toward updating Tower 1, modernizing the infrastructure and raising the computers to prevent water damage from flooding.
The tower houses a control system for the Massachusetts Bay Transportation Authority and Amtrak.
Transit officials say the tower's existing system is outdated and hinders service.
Signaling problems at the tower resulted in major service interruptions for two days in 2016.
So many trains rely on the tower's system that a brief shutdown can create delays affecting thousands of them.
The project is expected to cost $82 million. MBTA and Amtrak will pay for half.
