The Prague Public Transit Company (DPP) has initiated a transition toward zero-emission transport by replacing bus line 137 with the electric trolleybus line 52. This new service operates between Na Knížecí and Jinonice, utilizing the hilly terrain of the Malvazinky area.

The fleet primarily features new Bozankaya SNG 12T battery trolleybuses. These vehicles are designed for operational flexibility, utilizing traction batteries that allow for up to 40 kilometers of travel without overhead lines, which assists during power outages or line failures. The trolleybuses also include advanced climate control for extreme temperatures and utilize components sourced largely from European and Czech suppliers.
