If you are going to go to the trouble of hand laying track, for either scale appearance or personal satisfaction, depending on scale of rolling stock, .332 can be what, 9" tall rail?
Even current mainline isn’t 9", I don’t think.
I use 250 and 215, about 200 or 205 being the absolute minimum to use with factory mass produced flanges.
Track power?
Live steam?
Radio/battery?
Aluminium rail works well with the last two choices.
Llagas Creek, Sunset Valley, some others make rail of smaller profile than 332.
Almost every person I know who has tried to hand lay track in LS for out of doors use has given up.
Maintenance can be a killer.
Ties warp, shrink, expand, rot. Gauge goes all over.
Spikes do not like to stay in place.
Keeping spiked ties in place on turnouts can give you grey hair. Once they move, they move the gauge.
I know with Llagas turnouts, they use solid UV stabilized nylon ties, spikes run through pre-drilled holes, and mandrel bent over on the underside, and they do not move.
Smaller or indoor scales, we’d glue the ties down, sand them smooth, stain, spike, and ballast.
Outdoors, what are you going to connect all the bottom of the ties to?
There was a guy, local, many moons ago…0 scaler…got his buddies over, they spent the summer hand laying and spiking all his new LS outdoor railroad…worked pretty good…until spring came around.
The ties and shrunk and expanded, spikes all out, nothing would run.
Tore it all up and gave up.
Try a bit first and see how it works out for you.
