This video review takes a close up look at the HO scale Walthers Proto 2000 EMD SD45. There is a lot to like about this model; excellent application of road specific details, smooth mechanism and transmission, and a full cast metal frame. However, the original Tsunami was coupled to a poorly designed speaker enclosure. Inital sound quality was very poor. We had to replace the original speaker with Two Mini SuperSonics. While we had the locomotive opened up, we decided to install a LokSound Select Direct sound decoder and program the decoder with one of the newest EMD sound files from ESU.
