dear all experts and scholar,
i have a unique issue while preparing and working on network datasets. i have two datasets one for road travel and 2nd for rail travel, there are switches between rail and road to switch from one network on another network. this is about dataset i have. but i need a special kind of functionality for this network. condation1: when start point and end point both are on road network route must be on road network. condation2: when start point and end point both are on rail network route must be on rail network. condation3: when one point is on rail network and other on rail network then route use the switch between two networks to shrift. so far i am unable to implement these condations so far.
problem: the route do not follow above rules and draw a route which is more favorable[ATTACH=CONFIG]34566[/ATTACH]

1) Create a rail-only restriction and a road-only restriction on your network. If you know in advance where your input points are located (on the roads, on the rails, or on both), you can turn on or off the appropriate restrictions before running the analysis.
2) On the features that connect the rail lines with the road lines, invoke a large impedance penalty to discourage transitions between the two. This way, it's very likely that two points on roads will use only roads for the route, two points on rails will use only rails to connect, but a point on the road and another point on the rail will be forced to make a transition somewhere even though it's penalized.
