If you are using a 20m chord, then the stations to take measurements should be every 10m. Hold one end of the chord on station 1 and the other end on station 3 and measure from the rail to the string at station 2. The next measurement should be at station 3 with the ends at stations 2 and 4. Really you should have started at station -2 to have included station 0 or the beginning of the curve. I spent about 20 years calculating and staking out railroad tracks. We use degree of curve which is defined as the central angle subtended by the radii of a 100-foot chord. The formula is sin 1/2D(c) = 50/R R is in feet D(c) is degree of curve for chord definition. Our highway departments use the arc definition of degree of curve which is the central angle subtended by the radii of an arc of 100 feet. The formula for D(a) is D(a)/100 = 360*/2PiR or D(a) = 5729.58/R For railroads, the survey line is the center of the track or at half gauge.

It's a very useful app
Thanks for sharing this knowledge. It's too much helpful.
Thank you mam for this video... Learn alot about versine measurements... Could you make some more videos regarding sleeper testing...
Video accha hai...hm solve method ka video chhte hai
Thank you a looooot . May Allah rewards you goodness and paradise 🙏
Very nice teacher!
Very Thankful to you
Thank you very much,
useful information. thanks
Very clear explanation...thankyou
Beautiful
How to measure 1 in 20 turnout turn in curve which have approx 1250m radius then which chord will use to measure version
telugu lo pls
Question : Objects on a curve track like Balise, TVC Axle Counter etc, distance in between these object measuring in a or in a ,
is distance between 2 point
measure along a curved
Which is true
Thanks mam

Nice
Indian railways using 20metre length chord wire for versine measurement (i.e)length of station
Thanks
Any video to measure can't play tell me I'm in break down required to fight with p way
How to calculate versine in transition portion only?
cheated picture before started that video
Is Versine measurements apply to point and section also, if so pls share details.
Nice video,but practical need
hindi me bhi bataye
0:40
thats where u have ur basics wrong.
Those perpendicular need not to be radius necessarily
Hindi m hota to or achha hota ssmjhane k liye...
