With 3 Type 035s now in service (the Panther, Indy and Kinetic) NS is now looking at ways to unify the fleet. Work has begun on what is termed the Type 035M Project. This will be a major rebuilding of the 3 variants into a unified type (presumably to the larger Indy dimensions).
It is thought the programme will be completed by 2120 though no date has yet been given for when it will start. However the Panther will be 10 years old next year and is due its ILU (Intermediate Life Update) - which usually occurs after 10 years service. Its possible the Panther ILU will form part 1 of the unification programme.
