Instead of calling the tools directly from ArcPy, the tools are now methods of the na module. Removing the initials of the Network Analyst toolset also reduces confusion and makes it easier to remember the name of the method. See the difference as follows:

import arcpy
arcpy.CheckOutExtension("Network")
busStops = r'C:\Projects\SanFrancisco.gdb\SanFrancisco\Bus_Stops
networkDataset = r'C:\Projects\SanFrancisco.gdb\Chapter11Results\street_network'
networkLayer = "streetRoute"
impedance = "Length"
routeLayerFile = "C:\Projects\Layer\{0}_2.lyr".format(networkLayer)arcpy.na.MakeRouteLayer(networkDataset, networkLayer,impedance)
print 'layer created'
sql = "NAME = '71 IB' AND BUS_SIGNAG...
