Train commuters are facing delays heading to Melbourne's east, because tree branches have come down in strong winds near Heathmont railway station.
The branches brought down overhead wires on the Belgrave line and repair crews had to cut the power.
Metro says buses are replacing trains between Ringwood and Upper Ferntree Gully.
Buses are also replacing trains between Frankston and Stony Point because of a track equipment fault.
