All following container dimensions, and maximum weights are AVERAGES. Containers are smaller than truck trailers. In Canada, road maximum weights are 44,000Lbs cargo weight on 2 trailer axels (60,000Lbs on 3-axels) - beyond which, special permits and more axels are required. The container line shown is not necessarily who we will be negotiating with to sail on, and the line that is chosen may not have all of this equipment, and it may differ in sizes and maximum weights shown. Rail companies in Canada have reduced the maximum weights allowable (including the TARE weight of the container) to 50,000Lbs on a 20 foot container (with the ability to increase only up to 55,000Lbs when an additional US$350 is paid to the rail), and 60,000Lbs on a 40 foot contaienr (with the ability to increase only up to 65,000Lbs when an additional US$200 is paid to the rail). Please advise us what you expect to load in what equipment so we can properly quote the lines that can handle it.
