0.5mm is a scale 3 inches. Think - could you comfortably hold on to a handrail that large?

Most handrails are in the region of 1.5 - 2 inch diameter - a scale 0.25 - 0.33mm. The wire I generally use is 0.31mm...

I've found a good source of thin wire from SWG20  (0.9mm) to SWG34 (0.234mm) silver or gold finish, reels of 9M 1 also reels of 22M (sold for stringing beads in jewelry making)

Compare the price 2.20 for 480mm (4 pieces at 120mm) against 1 for 9M ;   9M/480mm = 18.75  so 2.20 * 18.75 =  41.25.
I rest my case.

Thanks guys I had already put a order into Nbrass for a few bits. Today I managed to pick up some florist wire for use with d&g couplings, plus I found some 0.35 piano wire in a model shop on my travels which was only coppers. No rush,
I have plenty to do over Christmas this year instead of watching the same old tosh. lol

I use ten thou guitar wire for my handrails. Not as easy to work or bend but I find the final result is more robust being made out of nickel coated steel.

Thanks Atso and everyone else. All these different  sizes are confusing me,only just getting used to metric. I will probably use the h/rail from n brass he as already posted the order off too me. The thing that confuses me is the pictures I have of 3f's the h/rail down the side of the boiler looks very large compared to the ones on the cab.

That's because on one side it's not a handrail!  ;)
On the driver's side of the loco you have the ejector pipe running along the side of the boiler (it should end in a junction with a vertical pipe running down to the footplate). There is a normal sized handrail in the equivalent position on the fireman's side.

Sure but how many handrails are you planning to make?

Plenty of uses for thin wire, I've never filed off cast hand rails in over 40 years of N gauge; if a new loco already has hand rails that's OK, but fiddling with hand rail knobs and wire is not my scene.
