I presume you get data from GTFS feeds. If so, it'd be more feasible to build a service that converts a 'poorly mapped' route into something better almost automatically. Manual involvement would be necessary to only correct defects from the process. Although we manually map, we reuse most route segments, especially trains where 2 similar lines could travel 80-90% on the same tracks. We just chop and screw where necessary. The whole thing takes a few minutes to draw a new route based on existing ones.
