CARL RUSSO PHOTOS: Brandon Berrios, a seventh-grader at West Middle School in Andover, loves trains.

They have fascinated him "since he was a baby," said his mother, Karen Berrios.

When Brandon's 13th birthday was approaching, his mom knew she could not have a conventional party because of the coronavirus crisis restrictions on social gatherings.

So she reached out to Keolis Commuter Services, which manages passenger trains for the MBTA. Kristin Selian from the agency's customer service center arranged for Brandon, who has autism, to have a train party at the Lawrence station late Wednesday afternoon.
