D,
     Need tips on soldering rail joints as I always melt some of the ties.  What solder and what soldering gun do you use?
                                  ///thanks in advance,

Thanks so much

I'm building a new DCC layout which will be 6'x16'.  Do I need power drops every 3' as with my standard DC layout?  The scale is N.

thank you

I am looking for N Scale engines with DCC installed from the 1960s to present day.  The US Army has 2 rail battalions active iin the US and I would like to find a source for the engines.
