Anne Marie and I were so sorry to hear today of Bill's passing. Bill was our longtime friend and my esteemed colleague at the CN Technical Research Center from when I started in 1960 to his retirement in 1983, and even later, after his retirement. He worked with me and others at CN Rail on many novel and diverse Mechanical Engineering research projects, including the development of the track geometry measuring "TEST Car" for the track Engineering Department.
We offer our sincere condolences to Bill's family.
Nelson Caldwell, Assistant Chief (Retired), CN Technical Research.
