Please undelete the milestones. The milestones adjacent to the tracks (at least those I personally placed) are real physical objects located manually. clay_c also did a rough import of mileposts from FRA data.

I took a quick look and see that you've deleted these "NY" mileposts: MP 4 east of Secaucus, MP 6 at Portal Bridge and MP 8 near Sawtooth Bridges. MP 8 was deleted back in June. NY MP 8 is not to be confused with JC MP 8 next to Harrison. The latter is still there.


I was able to use this Overpass query (using the bounding box) to snapshot railway=milestone nodes as of January 1st, 2025. The query is so narrow that Overpass has no problem if you query the entirety of New Jersey or something even larger:
[out:json][timeout:25][date:"2025-01-01T00:00:00Z"];
nwr["railway"="milestone"]({{bbox}});
out body;
>;
out skel qt;

Let me know if you need help restoring these. iD may be insufficient.
