I have two Bachmann SD-45 EL locomotives that came with DCC w/o sound. When I run them in DC, they start right up as so as I turn on the power. However, in DCC, I have to turn the throttle way up before they start to move and then once they start, they continue to accelerate. For example, in sped step 14, I have to turn it up to 12 before the locomotive begins to move and if I leave it at that level it starts slow and then accelerates until it gets to a normal 12 speed. I want to use them with a different locomotive I purchased from Bachmann, but it starts right up at 1 or 2 on the throttle and strains as it tries to pull the SD-45s until they eventually start and get up to speed. Can you tell me what brand of decoder I have and what might be causing the problem? I do plan to update it to sound. If it has a decoder with an 8 pin socket, can I just plug in a sound decoder or do I need to get rid of the original decoder to insert a sound decoder? I'm new to DCC so all the help you can give me would be greatly appreciated!
