Will a 6-35454 Amfleet CAB Control End car run on 0-36/0-31?

I am not sure if both will make it through the 036 curve, as it might be pushing the limit.

I had a set of Atlas 21 inch Amtrak passenger cars and they needed 042 curves and an SD-45 or equivalent engine's wheelset. My GP-9 worked ell with the 21 inch Amtrak cars until the curves, then it derailed everytime, coupler end play was what I forgot to take into consideration, so 'you may have' a similar problem.

I don't know much about the Lionel dash 9 diesel engine and what it may pull behind without derailing.

it will but it looks weird on the curves, sticks out way to much.  I run mine on 072 track and they work fine.  Ed P. 

They run fine on O36, but BEWARE, the overhang is pretty severe. You'll need lots of clearance on either side of the tracks. I normally run mine on O48 curves and it looks much better.

Amfleet cars (18 inch) have noticeable overhang on 72" curves
