Hi Kugelbaum,
Thanks for enhancing the trail network but I think you may have with this change  accidentally deleted and recreated with a wrong itinerary CFL 15A  (Maybe due to confusion with CFL15). You deleted relation 2251561 and recreated it as 18438053. It does not pass Dommeldange despite its name.
Did you find signs in the field that 15A starts in Mersch and goes to Mamer ?
 I noticed this today as I was in the process to re-map the CFL route  in the field around Dommeldange as it was clearly broken (on  intersection node  2344401844 in Eecherfeld it went in a wrong direction  not following anymore the clear signposts and not heading to the railway station).
Both routes are by the way as gpx on the CFL web but I did not want to use those due to the restrictive copyright.

Can you please check this and clarify both routes (I can by the way still try to fix it in Dommeldange after I followed all signs to the station provided that the route is undeleted)
