At the weekend of 15 and 16 October 2022, trolleybuses could be seen running on the new trolleybus line from Letňany to Čakovice. DPP also used the occasion of the launch of test operations in the above section to commemorated 50 years since abandoning trolleybus traction in Prague and 5 years since launching pilot operations in Prosecká Street, thereby effectively heralding, albeit more symbolically, the return of trolleybuses to Prague.
