Thinking of curve radii ...
SWB "tippler" wagons and the like ... 6" minimum radius (As say found in a quarry) Bogie passenger stock ...12" minimum radius (As say chugging up a Welsh hillside behind a double-Fairley)
... acceptable values??? Comments please as I'm currently drawing out new plans.
For guidance I'm thinking of having 040T SWB engines working a Quarry and
I believe the minimum radius on the FR running lines (the only place you would find a Double Fairlie on a Welsh hillside!) is 2 chains, and that is (was?) on the curve into the platform at harbour station. This scales out to about 21", so with normal modellers compression, you will probably get away with 12". For quarry stuff, you can use whatever you like - 6" does seem to be used for 009 layouts!

Cheers Paul, I'm not intending to run anything bigger than a W&L 062T ... it was the size of the passenger stock that I intend to use I was trying to illustrate. Your figures make sense though. I can easily make the visible sections of my passenger line 20" radius or thereabouts and the hidden loop
12" ... the way I'm designing it the quarry lines and the passenger line are almost entirely separate, only coming together (in any practical sense) at an engine shed.Have something to add? Share your thoughts — no account required.
