If names are same then let them be..Dadar has 2 different stations in WR and CR zone, but to avoid confusion, the names are set as Dadar Central and Dadar Western....While indianrail.gov.in has both the stations with the same name and same spelling...
So if there are two stations with same name just like New Delhi metro and New Delhi railway station, then we can bifurcate between the two by just adding metro in the name of metro station...
