Thanks for reply.
I understand rail road may not be really useful.

but if there is at least a way to mark Rail track and Driving road intersections.. (very common in India),
The can be used as references while driving.

also, the rail road indicates that travel from that road might delay journey by 15 to 30 minutes, if its time for train to pass by...

What I am talking about is a raod segment where a Car drives/crosses Railway track as if passing by node...

sorry for bad English.
Thanks in advance.

First of all consider whether it is useful to draw any kind of a railway because the railways are not displayed in the mobile client. Please search this forum for more discussions about the railroads.

There is no way to mark the railway crossing in waze, at least not to make it visible outside Cartouche. Also there is no way to mark manually that the trip may be delayed. This can be achieved by the live traffic report and collecting the speed statistics from the driving users to calculate the average speed but this is an automatic activity of waze. You can't do anything more as a human map editor.
