Generally in two foot multiples from 6ft to 12ft, but occasionlly odd sizes are found. The weight is the weight per yard but you should use these figures as a very general guide. In reality you tend to find a wide variety of rails with a mixture of patterns and presumably weights. Recycling apears quite common, so an old piece of cast iron rail might well be reused with wrought iron or even steel rail.
