Interpreting French Gradient Profiles
French gradient profiles are stated as X out of 1000 instead of the British system of 1 in X. So to convert the French system into a figure which is readily understood to the British railway enthusiast it is necessary to divide whatever number is shown on the profile into 1000. In addition distances quoted are in kilometres. Level sections of line are indicated by a thicker line than normal, normally without a number above but occasionally a 0 is to be found. The basic thing to remember is that the higher the number the more interesting the climb and once into double figures the climbs are starting to get serious.
The table below is presented as a quick reference guide:
