My condolences to both Dotty and Marty`s family. I first met Marty through several mutual friends at the York Show (about ten years ago). Marty & Dotty joined us a couple of times during some of the running sessions I had at my fathers house in New Hampshire. I remember Marty being impressed the with operation of the layout, being able to run multiple trains at once (command and conventional). Marty and my father also had the mutual interest in cars (particularly Corvettes).
Rest in Peace Marty! Til we meet again sometime and run trains.
