This is what it says in th manual.
View Rail Damage Info On/Off (hotkey r): Displays status of railroads in friendly and pending friendly hexes. The symbol is green for undamaged rail, red for damaged rail and orange for rail undergoing repair that turn. Rail hexes that have white dots within a green circle are hexes that have been converted but are not connected to the rest of the rail network or are rail hexes that cannot be used for strategic rail movement or supply purposes due to being adjacent to enemy units. In addition to rail damage, hexes further than 10 hexes or 25 MP from a railhead are shaded light gray, hexes further than 25 hexes or 100 MP from a railhead are shaded dark grey, enemy hexes are shaded rose, FBD and NKPS rail repair units are bordered in yellow, and all permanent supply source hexes are shaded in red.
First should it say ....10 hexes or 21 MP from a railhead are shaded light gray, ...
Next, this is what you get in with latest patch. The unit furthest east has a range to rail of 18 hex, way passed the 10 hex limit for shading light grey. The gey colour does not start until the MP range of 21 is reached. However the dark grey for over 25 hex etc does show correctly after pushing the unit further east.
