James R. Lovely, a railroad worker, was pinned between a 13-ton railroad car and a mound of earth at a Springfield industrial site for 20 minutes yesterday before paramedics arrived. The rescue workers said he was clinically dead.

"He had sustained cardiac arrest," said Lt. Randy Kennedy, a cardiac care technician with Medic Eight, a paramedic team based in Annandale. "There was no pulse and no respiration."

The rescuers extricated Lovely, 24, and used a combination of techniques to revive him. He was taken to Fairfax Hospital suffering from multiple fractures and abdominal injuries.

Lovely, of 317 Hume Ave., Alexandria, had been using a two-way radio to direct a train of eight cars and an engine backing into position at a dumping site on the property of Vulcan Materials in the Shirley Industrial Park, 5534 Industrial Dr.

About 6:45 a.m., a worker who had been in radio contact with Lovely said the radio suddenly went dead and he ran to investigate, finding Lovely already unconscious.

Kennedy said Lovely's fellow workers "told us they were afraid to move the car away before they knew how bad his condition was." So, when the rescuers arrived, they had the train pulled away from the earthen mound, freeing Lovely.

Then they administered drugs to stimulate Lovely's heart, gave him CARDIOPULMONARY RESUSCITATION (CPR) and fitted Lovely with a pair of socalled MAST trousers, which have inflatable tourniquets that cut off circulation to the legs in order to increase blood flow to the upper body. (The acronym stands for Military Anti-Shock Trousers.)

Lovely was listed in "very critical" condition at Fairfax Hospital's intensive care unit.

An investigation of the incident was continuing, but Fairfax County police spokesman Warren Carmichael said Lovely "apparently just got in the way of the railroad car and was pinned. We are classifying it as an accident."
