Lancer:
Great idea to add an upper level! Consider making it a passenger train loop with an automatic stop-and-go station at the midpoint -- well suited for a commuter line with Budd diesel commuter cars or a unique train like the MTH Aerotrain - the Rock Island version of which ran a route from Joliet to Chicago and return.
The loops at each end of the elevated route could be designated as a suburban zone on the left and "downtown" on the right. Or ... allocate one zone as a farm/ranch and the other as an industrial district. There are lots of available structures that would be appropriate to these zones.
Carry on, valiantly ...
