its a Koalin Clay Hopper,says Clay on the car side.
edit -- the car could also be used for Bentonite Clay service.
looks to be a Pullman Built car,but cant read the CUFT on the side.
rebuild a 2893 car by adding the heavier ribs,it will be a Stand In,
but should look fine.
Edit:
Ryan,this would just be a quick "Stand In",but one could get as involved
as they want with one or several of these cars.
Bachman and Atlas have made N 2893s over the years also.
believe that ConCor/Roco or Mini Trix also had a similar 2893/2915/2927
looking covered hopper in the foggy past.
