As the openstreetmap-carto updated, My pull request (#2687) now live on OpenStreetMap. Now the name from railway will be slightly rendered.

A three-level rendering is set (z11 for highspeed, z14 for main lines and z17 for all) to make it impact less to other elements.

After visiting Tokyo in July 2017, I found out that most of the rendering for OpenStreetMap is not that friendly to a railway-centric urban area, so I came with this request trying to fix that.

This is how Tokyo looks like, before and after, in z14:

I hope this rendering changes can inspire a better map rendering for railways on all other map styles. :)
