 Chenango Forks and as Mr. Sharwell left the train at Binghamton the

None of the refrigerator cars used are designed to cool the milk in

 and so is used for short hauls. The cans are set on the floors and in hot 

 weather have crushed ice packed around them. As the ice melts the 

 water runs out at the doors or through cracks in the floors. The other
