Are there any ex NH fgt cars in service anymore?
There is a small amount. I am thinking of the MW ballast cars rebuilt from 2 bay cov hopppers and maybe a heavy flat somewhere. I don't think there is anything else.
The X43E's were gone by the '80's, for the history buff, the last PC X43E listed on the CR roster was a white lined car, PC 127151. That was in 1986.
