Considering the wealth of experience on this forum....

What has been your most challenging N Gauge Modelling task you have undertaken and completed?

For me....breaking  the news to my wife I wanted to build one and then negotiating were it would be kept!

Got to say that "the misses" has been very supportive and quite appreciative of it since!

   Simple one this, building my brickworks kiln.
The other one was finding the money to pay for all the bits I have accumulated.

Wiring - the very thought of it and any sort of electrickery fills me with dread and foreboding I know I'm not going to harm myself with the small voltages involved, but I have to tackle feeds, points, signals and lighting at some point. Gulp!
I have read many books/websites but any wiring diagram just fuses my 2 remaining brain cells. I've jury rigged electrics to make sure everything runs as I want it to, but must soon make the wiring proper, and have the feeling the swear box will fill rapidly
Never had a problem with ladies/model railways as I always used the excuse "Well, at least you know where I am. I could be in town whooping it up (not Leyland, I hasten to add)"

Location, location, location !

I have spent my entire modelling life dodging the 'authorities' and trying to find a place to house my creations...
One day i'll get that holy grail known as a 'spare room' but until then everything has to stay portable.

Just need those 6 magic numbers.... 

On it at the moment. Getting the room and house ready for my first attempt
