The 4 and 5k cars,should be retained until sufficient replacement equipment is required.

The 4 and 5k cars are being retired because some of the member of the board were convinced that monies would be better spent replacing them with new. They also got cold feet on what it would cost to increase the fleet size to support 100 percent 8 car train peak service.

The original plan was to do a mid life rehabilitation of 4k cars to make them compatible with the 7k cars.

The origenal procurement schema for the 7k cars was as follows:
Base order64Dulles Phase I
Option 164Dulles Phase II
Option 2130Fleet growth to support 75% 8 car trains
Option 3100Mid life rehabilitation of 4k cars
Option 43001K replacement
Option 590Fleet growth to support 100% 8 car trains

After the Fort Totten wreck it became:
Base order64Dulles Phase I
Option 43001K replacement
Option 164Dulles Phase II
Option 2130Fleet growth to support 75% 8 car trains
Option 3100Mid life rehabilitation of 4k cars
Option 590Fleet growth to support 100% 8 car trains

After the dicision was made to replace 4 and 5k cars with new it became:
Base order64Dulles Phase I
Option 43001K replacement
Option 164Dulles Phase II
Option 3100Replace 4k cars with new
Option 2130replace 5k cars with new
Option 59062 to replace remander of 5k cars with new
Remaining 28 to increase fleet size
