Cyled here some weeks ago: 
The classification of ways 507969860, 507969862, 119961325 seems to be wrong: instead of unclassified, it should rather be track with tracktype = 3 or 4.
Unable to drive from one end to the other because of barrier=lift_gate. No buildings along these ways --> unclassified must be wrong  ( I did not make note of the exact position of the lift gate)
