Many thanks for the find, as always.

I am still convinced, however, that this is a bidirectional single wire line. Satellite imagery for different years consistently show overhead support poles along the southern side of the road only in many other places of the line. Poles on the northern side just not there. The clearest image is from 11.2017 in Google Earth Pro. Even in this photo poles on the northern side are not consistent and in places are missing.

I did not notice before, but it does indeed seem the second pair of poles only has a pole on the south side. With how the system has being observed (no trolleybus before 2.2015 image yet the only trolleybus never moving after) I feel maybe this network was never even properly completed/ opened.

This system was active and informations about them are very rare. But the system was closed in beginn of 2000s and actual no trolleybusses are exist there. There are also no trolleybus in western loop, its a service building. (but you could believe it on aerial pictures)

Thanks, Daniel. I will update the Mannyol page accordingly.

Any information on the Kumgol system you can provide?

Thanks.

Is it possible that the line could possibly extend further south, to the edge of the built-up area? The road quality is bad but it there is a spot that looks like it could turn trolleybuses around

Its possible, here is the furtherest west the survey team took a photo : http://www.cybernk.net/EV_CyberNKFile/im...nso.jpg at where you suggested.
Maybe it does go further (there are a few poles behind the sign here: http://www.cybernk.net/EV_CyberNKFile/im...ogj.jpg), but the image is poor quality and since it was likely taken in 2006, the line might have already been partially dismantled.

As for Kumgol-dong, that area is being prioritised for reconstruction.

Yes, so i write inside of STTS, that i will work at these trolleybuscities in next months. So after a lot of years catching each informations and talk in DPRK have some interesting facts. But this is a point which need time, and so it will go step by step. :-)

No, there was no longer track in this direction. The eastern end of this trolleybusline was in front of the cityhall. Maybe it will be a good extension, but never there was a realised trolleybustrack. (i also dont have informations about any planings)
