I have been interested in model railways since I was a kid.  I have an affection for rail travel and enjoy low key engineering and hobby electronics.  A degree in Physics means I can think through wiring diagrams and geometrical problems.  That's the strengths.

The weaknesses...  Little idea on actual rail operations, little idea on wiring "decoders", "DCC", "automatic points", "electronic train control".  No practice on scenic modelling, track laying, wiring points for "live frogs".  

So this will be an adventure into various and ultimately all areas of modelling a model railway.  Keep reading if you're interested in the mindset and challenges that face a new modeller.
