CryoTrans Refrigerated Railcar

CryoTrans called on Miles Fiberglass to help develop railcar liners for their refrigerated railcars more than thirty-one years ago.  Being a leader in the refrigerated railcar industry, CryoTrans was looking for a liner that was lighter weight, with greater impact resistance and easier to repair than their existing fiberglass liners.  They called on Miles to help them develop a composite liner.  After many months of working together to develop a design and product the first rendition of a fiberglass liner was developed.  Later, after researching different new materials, Miles approached Cryotrans about trying out a new polypropylene material, called Polystrand.  This material offered higher impact resistance and even lighter weight than the standard fiberglass material and easier to repair.  After many renditions, a Polystrand liner was developed.  With the development of the Polystrand liner, a 45% weight reduction was realized along with increased strength and impact resistance, by a factor of ten.  Removing the weight allows for heavier loads, leading to larger profits.  The high impact quality results in less repairs and down time also leading to more profits.
