Osmarender stuff

The following rules create the dashed lines:

 <rule e="segment|way" k="railway" v="rail">
   <line class='railway-rail' />
 </rule>
 <rule e="segment|way" k="railway" v="rail">
   <line class='railway-rail-dashes' />
 </rule>

And this is what you have to put into the styles:

     .railway-rail {
       stroke-width: 1.5;
       stroke-linecap: butt;
       stroke-linejoin: round;
       stroke: #000000;
       fill: none;
       }
       
     .railway-rail-dashes {
       stroke-width: 1;
       stroke-linecap: butt;
       stroke-linejoin: round;
       stroke: #ffffff;
       fill: none;
       stroke-dasharray: 3, 3;
       stroke-opacity: 1;
       }
