I would go with Iron Horse on the MP15DC I own two from Atlas in CSX with sound but no DCC. I am very pleased with them. A bit pricey but they are well worth every penny.
Iles said:The SW10 seems like a fun project and something I might think about tackling some time.
I suppose the Model 40 at Travel Town isn't really in industrial or short line use...but as far as I know it IS still in service and used regularly at their museum to shift around their equipment including other locos and passenger cars. Perhaps someone who volunteers there can chime in as to its status.Iles,First there is NO active Model 40s in industrial or short line use from my research..EMD only made 11.
There are certainly Baldwin switchers still in industrial use, but I don't know if there are any FMs. There certainly are some very old engines in use, like a couple Alco HH600s (!)You may want to consider a Baldwin or FM switcher as well.
