For years at Christmastime, the elder Mr. Geisendaffer enjoyed constructing a Christmas garden with trains for his children.
"The only equipment he had in the garden was all Pennsy," his son said, laughing.
In his retirement, Mr. Geisendaffer enjoyed vacationing in Ocean City and had traveled to Hawaii and visited the Old West and Grand Canyon.
"When it was possible, he liked to travel by train," his son said. "He also dedicated his life to helping his grandchildren."
Mr. Geisendaffer was a member of Hiss United Methodist Church in Parkville.
Services were held Wednesday.
Also surviving are his wife of 61 years, the former Audrey Robinson; a brother, Robert Geisendaffer of Boise, Idaho; eight grandchildren; and four great-grandchildren. His daughter, Marlene Hayes, was murdered in 1981.
