Tajikistan, the city of Dushanbe, where I am lucky to be on a business trip.
Few people have seen how trolley buses overtake each other :) and this is the usual thing...
It all depends on the driver and driver.
At the stop, the conductor hangs on the ladder behind the trolleybus, the trolleybus accelerates faster than the slow-going trolleybus ahead and here the brave Tajik conductor disconnects the trolleybus bars from the wires, the trolleybus by inertia outputs the other and the conductor puts the bars in place.
