When anyone posts a question about DCC, and specifically engines, please tell us what scale, who made it and what model it is. It makes it easier to answer to the correct scale. Some guys model mostly HO and N but it's nice to know the difference because these models differ in the way DCC is applied to these scales. Like decoder installation and getting a model DCC ready. I'm not leaving out any scale. It's just that MOST questions on DCC is either HO or N scale. I'm sure there are S,O, TT, Z and others that use DCC also but they are the ones best suited to answer those questions. Thanks. This would make it better to get the right responses instead of guessing. It would help us, help you.
