James T. Lloyd, a transportation lawyer who retired in 2002 as general counsel and executive vice president of Amtrak, died Dec. 19 at his home in Bethesda. He was 72.

The cause was metastatic prostate cancer, said his wife, Juliette Lloyd.

Before joining Amtrak in 1999, Mr. Lloyd had been executive vice president and general counsel of U.S. Airways and in private legal practice in Washington, specializing in transportation matters.

James Terrance Lloyd was born in Wichita. He graduated from Kansas State University in 1963 and from Dallas-based Southern Methodist University law school in 1966.

He worked briefly for the Civil Aeronautics Board, then joined the law firm of Hydeman and Mason, where he later became a partner. In 1985 he joined the Washington office of the Seattle-based firm of Preston, Gates & Ellis.

He was with U.S. Airways from 1987 to 1996, a period in which the airline broadened its base from a short-haul Northeastern carrier to a national operation.

After nine years at U.S. Airways, Mr. Lloyd returned to private practice with the Bryan Cave law firm. There, as a member of the board of directors of Reno Air, he helped negotiate the acquisition of Reno Air by American Airlines.

His marriages to Colleen Unser and Jane Keller ended in divorce. Survivors include his wife since 1993, Juliette Chiodo Lloyd of Bethesda; two sons from his second marriage, James T. Lloyd Jr. of New York City and Kevin M. Lloyd of Huntingtown, Md.; a stepdaughter, Christina Heintze Witmer of Annapolis; and a grandson.
