[Buses in Beijing]青年尼奥普兰-华宇 Youngman Neoplan - Huayu JNP6120GD/BJD-WG120N <Trolley-bus> 北京公交集团 BPT #85228 Rear-left at Erligou

A JNP6120GD/BJD-WG120N low floor trolley-bus jointly built by Youngman Neoplan, Zhuzhou Electric Locomotive Research Institute (generally considered as CSR Times today) and Beijing Trolley-buses Plant

 

Based on a Neoplan Electroliner body introduced by Youngman Neoplan, JNP6120GD is the first mass-produced 12m low floor trolleybuses with AC motor in China. “JNP6120GD” is the model name from the main builder, Youngman Neoplan, but since Youngman is not qualified as a trolley-bus manufacturer, JNP6120GD is registered as BJD-WG120N, under Beijing Trolley-buses Plant, which also builds trolley-buses on its own basically for Beijing. Power comes from a 100kW (134hp) asynchronous induction motor made by Zhuzhou Electric Locomotive, which also provided the control system with VVVF switch. The auxiliary power source is a lead-acid battery pack, storing electricity during regular run for off-wire operation when proceeding along or across streets where mid-air wires are not allowed or inconvenient to pull.

 

100 units of JNP6120GDs were assigned to Line 103 and Line 108, two most important trolley-bus lines in Beijing, in December 2006. The fabulous trolley-buses’ debut invited enormous approval and praise for their elegant styling, low floor design, absorbing ride and extremely low noise. Time verifies that their quality is worth trusting. What attracts bus fans is the gripping sound given out by the AC+VVVF power train.

 

In the picture is Fleet No. 85228 (Trolley-bus Division, trolley-buses, code 228) on "National Workers' Pioneer Bus Line" Line 103 waiting for the green signal at Erligou crossing. The bus is facing north, heading for its final stop Beijing Zoo Public Transport Hub. At this crossing, trolley-buses on Line 102 and Line 103 leaving the Hub turn from east, Xizhimen Outer Road South (one-way street) to south and pull into the second stop, Erligou. Trolley-buses heading for the Hub travel north and turn east on Xizhimen Outer Street.

 

The pull-ropes of this unit are loosely tied onto the rope box, but not all trolley-bus drivers in Beijing even tie them. Many of the drivers just tie two ropes together and put the end into the side window. According to the drivers, it is too time-consuming if they must untie the rope from the rope box in case of poling failure.
