What's the average weight of an individual train RAIL?

Question

By meter. I need to get the weight of a 12 meter rail.

Answer 1

Rails come in several varying weights.  The heavier the rail, the heavier the application it's suited for, such as higher speed and/or heavier trains.

Rail weights are in pounds.  In North America, weights can vary from 90 lbs. (industrial sidings, yard tracks), to 120 lbs. (main line), all the way as high as 135 lbs. (high speed/weight main line).

The weight grades are how much a yard (3 ft.) of rail weighs.  To convert this to metric, just follow this equation:

(Weight in pounds / 90 cm) x 100 cm = weight of meter of rail

Answer 2

112 to 145 lbs per yard.  Sorry, you'll have to convert to kg/m  My numbers are probably for track used in the Americas, and the weight varies with the size and speed of the trains using the track.  Small spurs and little yards would use lighter rail, main lines would use the heavier.
