I have a n-scale oval on the console underneath my TV.  The curves are 282mm radius.  I want to put another oval inside this one with 249mm radius, and connect the two with a double crossover.  I have DC power.  Should I power each oval with separate power sources to provide separate speed control?  If so, how do I wire the crossover?

I have been unpacking all of my rolling stock and engines over the past week and checking them all out for performance. I came across a Rivarossi (AHM) 0-8-0 engine that was in pretty bad shape but I worked on it for 2 days and got it running. If I remember correctly I bought it in a junk box of other items and it is missing parts (2 front drive rods). Searches of the web got me the parts diagram but no parts available. So I side lined it and began unpacking more stuff. Lo and behold I came across another Rivarossi (AHM) 0-8-0 engine - brand spanking new. works like a charm.

Within the past week, I have encountered a low voltage short on my railroad. I use an NCE dcc system and have the railroad divided into 6 power districts - this short only occurs in district two - the main yard. Any locomotive that enters the district produces a nice warm glow on the cp-6 circuit protector and as you increase the throttle, the glow gets brighter.

Anyone have any thoughts before I begin the hunt this weekend?

Thanks,

Installing DCC into older steam engines often requires multi-wire connections between tender and engine.  For those who cannot leave engines permanently coupled, there seem to be few connectors offered directly to the hobbyist.  Depending on scale, some of these connections demand higher power connectors than others, while all can be challenging to fit into the limited spaces.
