I have a friend who loves trains, absolutely loves them, but he won't spend money to indulge himself in this hobby so I'm going to start him off. He has a family member that makes O scale models, and I've read good things about this scale so I'm sticking with it. Given that this scale is quality oriented, I was looking around for what most model rr people would call the most beautiful model(s) of all but unfortunately I can't find much on this topic. What I did find were a few pages that claimed that the Southern ps-4 (as in the 1401 type in the Smithsonian) was arguably the most beautiful of the steam locomotives. Now from some research I've done I've concluded that Atlas O Master seems to be top of the line where quality is concerned so I'm looking for a ps-4 Atlas O Master but can't find one. Does anyone know if it was ever made, or if there is an high quality alternative? I would also appreciate some advice on how to purchase these type of models... I would like him to have the option of sounds and command control but I don't know if I have to choose specific models that support these techs or if they are independent of the models.
