All T3SUCS in Prague are supposed to be replaced with a new type of tram - Škoda 15T within the next few years.

More than a hundred 15T's were delivered (to Pankrác and Vokovice depot), and many of T3SUCS were already put out of service, stored at yard of workshop-depot in Hostivař, and offered to purchase.

However, due to technical issues of Škoda 14T trams which had to be withdrawn from service,[2] some of the old T3SUCS are now temporally back.

The T6A5 model is also old and not much prospective; those cars located in Žižkov depot were built in 1996 and 1997.

Elimination of this model is expected since the last of 250 15T's will be delivered in 2018.
