Bruce is indeed correct. That is a c.'55-'60 ACF welded jacket and frame tank car. You can tell by the rounded stub end sill typical for ACF products of that time. It also has the rounded insulated tank ends they did typically for their more-"standardized" products.

I think that the second car is in fact insulated. If you look closely, you can see the tank bands appear to disappear just about the turnbuckles. That car is much newer.

Gentlemen, I'm no freight car expert but the two Warren cars appear to be different. One appears to be insulated (Obviously a Sunshine kit;>) With the black or dark lower band while the other appears to be non insulated and no dark band at the bottom. I'm assuming Warren had both types.
