KT8 KB
I am from Germany and will visit Košice next week. I want to take a ride at the KT8 vehicles, there are only 509 and 523 active at this moment, an the T6 vehicles. (2 trains run this moment, 620/621 and 622/623)
I read, that there is nearly everyday Mo to Fr one T6 and mostly 523 at line R4. Does one of them go to USS Steal or do they have the final stop at OC Optima or even before? I know, only the KT8 will end at OC Optima because of the switches behind the stop.
I was in Košice for about 7 hours last year an unfortunately there was the 523, that went to the depot from OC Optima around 15:30.
Until which time around are the KT8 and T6 normally on the lines?
Thank you for your support
