Curve Radius

May 01, 2007 3 Replies

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 of track. Add 50mm+ to calculate the outside clearance required by rolling stock.

I think it shows the dimensions for track at the back of the Hornby catalogue ?

Good luck
