Monthly Railway Carloadings Survey
Summary of changes
Activity on this program started: 1921
The method of collecting the data changed from a paper questionnaire to an electronic questionnaire.
In 1999, the monthly Railway Carloadings survey was affected by the implementation of Standard Classification of Transported Goods(SCTG). The categories of the current publication consist of an aggregation of the SCTG categories. Comparison of the new and old series of goods is not necessarily appropriate. The impact on bulk commodities such as wheat, potash and coal are negligible. However, the comparison of residual categories or of manufactured products categories is not appropriate. It is also worth noting that, starting in January 1999, the number of carriers surveyed has more than doubled from the eighteen carriers surveyed previously.
