Tom Marr was another WFBR colleague who later worked with Mr. Maylath at WCBM.
"He was a newsman's newsman, someone you could always count on," he said.
After WFBR was sold in 1988, Mr. Maylath migrated to WCBM with former colleagues.
He retired four years ago.
Mr. Maylath's infatuation with railroading no doubt began in Croton-on-Hudson, N.Y., where he grew up and where the old New York Central Railroad maintained extensive yards and shops.
"Trains were the passion of his life, and he had traveled all over the U.S. and in other parts of the world by train," said Mr. Marr.
Mr. Maylath — who wrote numerous articles for "Interchange," a publication of the Baltimore chapter of the National Railway Historical Society — wrote and edited a monthly publication during the 1980s on passenger train news.
He was also been a longtime volunteer at the B&O Railroad Museum.
"He was here on Friday, the day before he died, so we're all in shock," said Courtney B. Wilson, who is the museum's executive director.
"He had been volunteering here close to 14 years. His great expertise was in passenger trains. He had a great depth of knowledge of passenger, parlor, dining and sleeping cars," said Mr. Wilson, who added that Mr. Maylath was never without his B&O cap.
He said that while Mr. Maylath was "quiet and reserved," he easily "engaged with museum visitors and families, who were soon fascinated with him."
Mr. Maylath was a member of Hiss United Methodist Church, 8700 Harford Road, where funeral services will be held at 11 a.m. Thursday.
He is survived by two men who considered Mr. Maylath their father, John Phillips and Larry Hartman, both of Parkville; and their four children, who considered him a grandfather.
