When Peco, for example, say their 4th radius curve is of 572mm radius, where is that measured to ? Is it the centre line of the track, or the outside rail or outer line of the sleepers ? Thanks chaps and chapesses.
Centre line, I believe.
Centre-line of track. Add 50mm+ to calculate the outside clearance required by rolling stock.
Why not try WinRAILWAYS software Version 4.1.0p1 - November 2006 @
NOTE This software package is NOT FREE software. This is SHAREWARE, that is TRY BEFORE YOU BUY.
I think it shows the dimensions for track at the back of the Hornby catalogue ?
Good luck
