I am having a similar problem --Without NAM all my trains are running fine and the route query tool shows that 1189 sims use one particular station. After I install NAM I get lots of commute time ZOTS and the route query shows that only 4 workers use the station (except if I route query the track post-NAM it says 1189 passenger train).
I've tried uninstalling NAM and the trains start to work again and houses become full. Reinstall NAM, same thing happens. I've tried installing NAM with different settings 'A' and 'Z' but neither of these work either.
Has this happened to anyone else?
