Sorry, I made a mistake in the previous changeset https://www.openstreetmap.org/changeset/145957804.

I corrected it according to the instructions at https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dcrane.

The crane track should be tagged as:
```
   man_made=crane
   crane:mobile=rail
```

I accidentally missed one track (a total of 35 tracks), which was also corrected in the changeset https://www.openstreetmap.org/changeset/145958376.
