HI @sweref.
I made a slight change to the workspace (added a Snapper and adjusted the tolerance a bit) and got all 11 routes.
See attachment for the changed workspace: networkanalyst-mod.fmw

Hi @sweref, the reason is that the road lines don't form a single connected network. All the lines belonging to the same network should touch adjacent line at their end nodes. You have to build a clean network firstly.

Hi @erik_jan, I think the snapping tolerance (500) is too large. It could destroy original shapes of most lines.
With the original 300 one route was not created. Could need some fine-tuning or cleaning up the network in advance. Concluding: the routes not being created is due to the not connected network as you already mentioned.
