Train and Light Rail tracks currently do not appear in Waze client, but may in a future release. For that reason some editors may map at least the portion of the railroad that cross driven roads. However, it is '''not''' necessary to create a junction between the driven road and the railroad. The Waze routing engine will properly calculate the average time through a segment regardless if the railroad creates a junction on that segment or not. By not creating a junction there is less chance for turn restrictions to be set incorrectly and potentially cause automated errors in the system.

'''Railroads should be labeled as such in the editor. for the time being they won't make it to the client indeed, but in the future we might want to use them for display purposes.
