I have a problem: My layout is divided into blocks for either DC or DCC operation. There is one block, with a curve leading into a 3-1/2 percent grade. Because of the long grade, I haven't paid much attention to any slowing on the straightaway grade. But on the curve leading into the grade, I see notable slowing as the train enters the curve. I have checked rail joiners and have soldered a few. Yet, when I finally started checking voltages, I find there is a 0.2 DC drop at 6 v. between adjacent blocks! Can't quite figure it, but am going to do voltage check from the control panel to the block. I think the next thing would be to compare voltages on DCC. As the wires are the same for both power sources to the block, if I see a comparable drop exists. If so, then I may need to add heavier gage wire from the control panel to the track. The wire run is about 8 feet, but I don't seem to have the problem with other blocks that are further away. Any comments, suggestions? The meter is a standard analog type.
