A lot of research and phone calling finally seems to be resulting in some discoveries. I have been advised that there is an intact ALCO-Sulzer engine still sitting in a building, the 1930s vintage engine was decommissioned more than three decades ago, and is secure and has not been vandalized. I have talked with the officials of the organization that owns it, and they seemed receptive to a visit. It is a considerable distance away, so when I can arrange to go and take a look at it I will post a report if it appears worthwhile to do so. I do not want to subject cooperative hosts to a string of requests for special visits, so for now I am not going to provide any location information.
