WMATA: 7k cars are not composed of 2 married pairs |

Posted by Sand Box John on Sun Jul 25 14:57:25 2010 It has come to may attention the reason why the 7k cars can only be run in 4 cars sets. The 2 pairs of cars in the 4 car sets are not composed of 2 A-B married pairs, they are composed of 2 dissimilar pairs, the first being an A-C pair and the second a C-B pair.As most here know, various components and systems are shared across WMATA's married pairs. The 7k cars will sill share those various components and systems between the A and B car, cabless C cars will be placed between the A and B car creating a A-C+C-B train set. WMATA's also plans to rehabilitate the 100 4k cars to be compatible with the 7k car. I don't know if plans call for converting half of the cars to C cars, retaining them as A-B married pair with no cab in the B car or simply leave them as is with cabs in both A and B car. If the ladder 2 are true then it will be possible to run 7k cars with 4k cars to dispatch 6 car trains when capacity requires shorter trains. John in the sand box of Maryland's eastern shore. |
