TVA has not scrapped it’s trainmaster at the Gallatin Steam plant. This plant does not get it’s coal by rail right now,but this situation may change. There was a lot of talk herabouts ( I work in Nashville ) of CSX once again bringing coal to this plant. It seems they had worked out some problem that allowed them to be price competative with river barges. The last I heard the mayor of Gallatin was fighting the proposal with the TVA board, then the whole thing just dropped out of the news.
The FM Trainmaster was a pretty interesting beast. They lost out because they were 10 years ahead of their time with the big horsepower locomotives? At very least, FM should have been able to sell some Trainmasters to UP.
FM got off to a very, very poor start on UP with their first set of cab units, which more or less blew up out in the high desert due to due to problems with heat and thin air.
They did go for a few more units, notably some H-20-44’s but only under very favorable purchase conditions.
By the time the Train Master came along, railroad motive power managers ( at least the brighter ones) were beginning to understand the economies of polyglot locomotive fleets (training, down time, cost of parts inventory, etc) and were beginning to back off from minority builders, no matter how good the product.
The TVA unit is an H-16-66 unit and not an H-24-66 unit. It is therefore not a true Trainmaster though it looks the same. The H 16-66 units are the Baby Trainmaster though some also incorrectly call an H-16-44 in the later carbodies Baby Trainmasters.
