Grade Signs
Grade signs are rectangular signs with partly blue coloring that can be found on the right side of the tracks, with a number informing of the grade of the tracks. The information applies to the section ahead of the sign, all the way up to the next grade sign or a switch, whichever comes first.
The grade is represented in percentage (%). An incline of 1.2% positive grade would be marked as "+1.2" on a yellow background with a diagonal line going up. A decline of 0.6% negative grade would be marked as "-0.6" on a red background with a diagonal line going down. A sign indicating that the grade is between -0.5% and 0.5% will show no number on a white background with a flat line.
Installing a clinometer gadget allows monitoring the current grade in real time.
