Western Railway commuters who stay beyond Virar have sought 15-car local trains till Dahanu, after the WR told them that it may not be immediately possible to add services due to line capacity constraints. But the railways have told them it will be possible to start 15-car locals from Dahanu only after the route is quadrupled. 

The Western Railway line between Churchgate and Virar is quadrupled, but between Virar and Dahanu, there are just two lines while two more are under construction.
