The Nampo trolleybus has again been captured in motion on satellite.
2 trolleybuses leaving depot plus 1 near the east loop
However, comparing 12/24/2020 with 5/6/2021 shows all other trolleybuses parked in the same position.
I doubt that they had parking skills to park the trolleybuses in the exact same position between 6 months. Perhaps this would explain the number of standard buses in Nampo, seen on all roads, covering the whole trolleybus line.
I can't say for sure, but a bus parked close to the trolleybuses looks like the solar panel bus, it has a very reflective roof
