Just bump out a bulge to accommodate whatever size curve you want. I use bump outs for many purposes.
Adding passing tracks, a second curve, control centers, additional sidings or buildings, passenger stations, whatever. It can be an added on blister or something knitted one piece into the existing benchwork.
You only need to bump out enough for the track.
The top bump out was for a switcher run a round.
The above curved plywood edge makes a nice curve bump out.
The darker surface above is the additional bump out.
Bump outs can also be used for tools, power packs, widgets and snacks.
