The consortium of ZELW and SIEMENS won the purchase
order of 168 metro cars (6 cars to make up one train, 28 trains
in all) for Shanghai Metro Pear Line Phase 2 in 2002. This
line has an overall length of 22km with 17 stations, all underground.
The train is made up of 6
cars, including two trailer cars (A car) with
driver's cab and 4 motor cars (B car and C
car) as following (Figure 1):
£¡¡A * B * C = C * B * A £
A- Trailer car£¨with driver's cab£©
B- Motor car£¨with pantograph£©
C- Motor car
A¡¢B and C make up separate set of car
Connection between cars is realized through
couplers with energy absorption ability.
-Automatic coupler
= Semi-automatic coupler
* Permanent coupler
