Re-icing reefer cars

Here are two photos showing equipment for re-icing refrigerator cars.   The first photo shows a truck mounted machine for crushing cake ice into snow ice, which is then forced into the refrigerator car through a hose.

The below photo shows re-icing a refrigerator car using a hose from the ground.  I don't know if the hose in this case is being powered by the machine on the truck but it is likely.  You can see the word "ventilated" on the side of the reefer.

I am almost finished constructing the main building for my ice machinery factory and will post a photo soon.
