I think you are taking a general public consumer view of the map. The 
main value of maps is often for planners, and researchers, not for 
travellers.

Whilst rail planners will already have more detailed maps, and other 
planners might occasionally benefit from the information, but the other 
big factor is that a great deal of information goes on OSM because 
people are enthusiastic about particular subjects, for which maps may 
exist, but are not generally published, e.g. people collect information 
on sewers networks.
