I was looking into grain transport and could not find any info in covered hoppers for grain transport. I did see information on grain shipment using Falns or Fad open hoppers. For covered hoppers I had to dig a little deeper and found the Kmmfks and Hbis type. Since grain is a very moisture-sensitive commoditie and the lack of info on covered hoppers had me in doubt. Are grain transported in open hoppers regularly since there are not enough covered hoppers? Or they are only used in surge traffic, therefore more visible to the general public (along with news of unusual high grai yields)?
Thanks in advance,
