Seems to be a decent upgrade
Also judging by the pylons beside the future track, it seems it may be electrified which despite being expensive initially for a developing country, makes perfect sense for a mountainous nation where continuous torque from electric motors helps big time.
The only problem is that none of the proposed extensions will run into the Somali region. Seeing as how Ethiopia is an important stakeholder in regards to Berbera port, it would've made sense to extend the line to Jijiga and halt it there till developments in Berbera/SL kick off and then extend it to Berbera via wajaale.
Yeah it's okay, but I think the Chinese are definitely much better than the Turks. I don't see much skill transfer going on going by the pictures they are posting, but maybe they are and just not taking a picture of it.
And the Addis->Djibouti railway goes through a part of the Somali region, but yeah that's it.
