Samarkand — Tram lines and infrastructure
Rudakiy ko'chasi
Трамвайная подстанция возле туннеля на улице Рудаки, которая на данный момент не работает в связи с отсутствием подключения к сети после реконструкции развязки. Из-за этого напряжение на контактную сеть подаётся из трамвайного депо, что заставляет вводить ограничения на работу по линии: выпуск не более 5 вагонов с максимальной скоростью езды по участку 15 километров в час

České Budějovice — Trolleybus lines and infrastructure
Lidická třída
Typical Czech-style trolleybus feeder connection, including manually operated 2-pole disconnector and dual surge arrester (top).
In this case 2 cables are run for the positive and negative supply, presumably due to the distance from the nearest traction substation (circa 4 km).

Dong Shan Kou, Inner loop Rd.
Trolleybus wire switch near Dong Shan Kou, Inner loop Rd. Westbound. This switch type is the most common design in China. Probably manufactured by a factory in Yangzhou.
This is a traditional type trolleybus wire switch that is triggered by electric current. To trigger the switch, the driver steps on the accelerate pedal when the trolley pole is under the switch. Otherwise, the driver cuts off the current (coasting) to go straight.
There are 2 switches in series here. This is the second one.
Switch 1 Coast: Inner loop Rd. (Route 106)
Switch 1 Trigger/Switch 2 Coast: Zhongshan 2nd Rd. (Route 107)
Switch 1 Trigger/Switch 2 Trigger:Nonglin Xia Rd. (Route 112)
