A field survey of freezing problems was initiated to obtain information regarding experimental and analytical studies, field trials, product or equipment evaluation, descriptions of the type and severity of freezing problems, current practices and their effectiveness, possible operating cost estimates, and current energy utilization in thawing and/or dislodging frozen bulk materials being shipped by rail during winter. A questionnaire was distributed to companies in Canada, the United States and Europe in order to establish guidelines for the field survey. A summary evaluation was made of the information received. This evaluation formed the basis for the selection of sites to be included in the field survey portion of the program. While the approaches taken at a number of locations in Canada and Scandinavia are detailed in the report, one inescapable and seemingly obvious conclusion resulting from this study is that there does not seem to be a universal solution to freezing problems of bulk materials during rail transportation. It appears that each solution must be individually engineered to meet local conditions and economic requirements.
