Police were called to the scene just after midnight on July 3. Railroad workers found the little ones, apparently just 9 months old, alone by the tracks, Worcester police said in a statement. After they called 911, paramedics took the boys to a local hospital.
"I saw the little baby wave at me," said Providence and Worcester Railroad engineer Eric Martell, according to NBC4. "I saw his little arm, he started sucking his thumb, and I was like, 'Oh my God, there's a baby in there.'"
Martell said he found the boys in a double stroller and they were wearing shoes. They were left with bottles, and one of the boys had a pacifier.
"One of the little guys looked up to me, gave me the biggest little smile and I was like, 'It's going to be alright, buddy. It's going to be alright, I got you,'" Martell said, according to the outlet.
The children are in the custody of the Department of Children and Families.
Worcester Police Detective and the DCF are continuing to investigate the case. The babies have been identified, but it's not clear if their parents have been contacted or charged, NBC4 reported.
Anyone with information on the kids or the incident is asked to call Worcester Police Detective Bureau at 508-799-8651.
