>>1813091>shithole country problemMight be. I wonder where's the difference. We do have new trolleys but the wiring design doesn't seem to have changed. OTOH on some new routes there are very few junctions. The wiring simply ends at some stops and continues at next stop after obstacles. The bus will cover that distance on diesel and automatically re-engage centenary when stopped.
Might also be also density and planning problem. It's capital and center is crisscrossed with bus routes. If you have favorable agglomeration and just a few routes you could possibly plan them out to connect smoothly without any mid-road junctions and intersections with other bus routes, trams and trains. Cuz damn those wires look ugly.
