Talltim Posted January 18, 2015 Share Posted January 18, 2015 I was reading this article on the Claren Chailly Blonay in Vaud http://dx.doi.org/10.5169/seals-30120and on the second page there is a gradient chart, copied below. This also shows the curves, left or right and gives a figure in 'courbes cent a gauche' (or droit). This translates as 'curves percent left', but I'm not sure what this actually means. Is it the amount the curve turns from the tangent, or something to do with the radius? I notice that some of the individual curves also have an Rxx figure which I would imagine is radius. Can anyone explain it to me? Other things that puzzle me are the significance the of the Evitements and the smaller flags, possibly these denote signals as I know there were some where the line crossed the Route Cantonal just below the only tunnel.

Grovenor Posted January 18, 2015 Share Posted January 18, 2015 I think 'cent' is short for centered and it is just indicating, by the offset of the line whether the curve is turning left or right, the figures shown for each curve will be the radius, in meteres I would think. This is a pretty standard way of showing curves on line alignment drawings. The smaller flags look to be just marking the gradient changes, evitement has the same symbol as stations so could be block posts, the other bullsye symbols appear to be places where the track design changes as shown on the dotted line with 'voie posee' etc. Regards Keith Link to post Share on other sites More sharing options...
Talltim Posted January 18, 2015 Author Share Posted January 18, 2015 Thanks. The smaller bullseye are,as you say, the markers for the changes between on-street and dedicated trackbed Link to post Share on other sites More sharing options...
chb1988 Posted January 24, 2015 Share Posted January 24, 2015 About the smaller flags, they are marked p.n. which means passage à niveau or level crossing. I was about to say that you wouldn't have signals on such a small line, but then I came across the below picture: source: http://www.eingestellte-bahnen.ch/636/19785.html Link to post Share on other sites More sharing options...
