Hi Michael :wave:

When I started out making 1:35n2 stuff, I began with 2 locos, a Shay & Porter.

The very first thing I scratchbuilt, was the LONGEST and WIDEST car which I thought would be running on the railroad.

It was a 'Heavy Duty Flatcar' & is 6' x 17.5' over the end-beams.

I now have a Mogul to convert as well, this is slightly wider than the Shay & Porter, at 5'6" in 1:35n2.

I am following the 'rule of thumb' John mentioned, that 3x the gauge is the maximum width.

In general my 1:35n2 carbuild sizes are scaled from Gilpin Tram blueprints.

In fact the 2' gauge Gilpin Trams widest car, the caboose, was 6' wide & 14' long

A Gilpin Tram ore-car is about 4' x 14', a very few of their cars are longer, up to around 20', but not many.

These longer cars are also much narrower than the caboose, about 4'ish I seem to recall.

Recently I have been working towards some kind of 1:35n2 trackplan.

I have found it quite difficult to draw this AND understand fully the size of buildings etc.

I decided in the end, to experiment using real track pieces.

I adopted the standard track geometry pioneered in the U.K. by Tri-ang Railways(TM) back in the swingin' '60s.

This exact same geometry is used to this very day by many other manufactures as well, including Peco, Bachmann & Hornby.

Basically the track has 4 different 22.5 deg. radius sizes.

All of these plus the switches & crossovers are all designed to give a final track to track centre spacing of 67mm.

This geometry is proving useful in figuring out a good 1:35n2 trackplan.

I now have numerous Hornby track pieces to experiment with in 1:1

This is the most popular track in the U.K. a bit like Atlas in the U.S.

There is a busy and affordable market buying & selling it on eBay.

67mm is quite narrow for a 'real' track spacing & possibly will not actually clear on double 67mm spaced curves.

But I don't plan on having too many 'double track curves'.

The 'straight' clearance is OK for 1:35n2 however, a bit TIGHT though.

The Hornby switches & sections will likely only be used for constructing staging yard/s in the end anyhow.

Which will be straight and the tracks as close together as possible.

In the end, having some flextrack & perhaps some setrack pieces to experiment with, I think is a good move.

Also having a footprint for your biggest car could be good.

Even if it is only for now a cardboard rectangle, cardboard rectangles are actually pretty useful !
