A covered hopper?

As you read this, a covered hopper is already installed on The Omega Scale Railway. Again, we are very proud to have another common car type on the layout. This actually gives us a variety of rolling stock. Omscaler loves variety. Variety is the spice of life. Back to the covered hopper. Covered hoppers were used to haul commodities that would be damaged if it were to become wet. Cement powder comes to mind. Perhaps you, the reader can do omscaler a favor and use the comment section to inform us what other commodities were transported using a covered hopper. Also, all readers are invited to comment, good or bad, on the blog. Hoping to hear from You. until next time, omscaler
