Unfortunately i didn't think to take any photos, but i just checked the lantmäteriet topo map (i had completely forgotten about this note) and that indicates a crossing (the version we're allowed to use sadly has limited zoom so it's quite blurry).

But i do mostly remember what the crossing looks like, basically a wooden platform around the tracks with a simple stile on either side.

Shall i just map the paths and crossing with the information i can accurately place?  
I might back here later in the year and this time try to remember to photograph it.
