For the average good wagon we assumed that 65% of the transport is performed by closed wagons and 35% by tank wagons. 50% of the wagon in each category are 2 axis vehicles. The life span of one wagon is assumed to be 40 years with a yearly kilometric performance of 21148km, resulting in a life time performance of 845'900 kilometres. The total weight of a wagon is assumed as about 27t)

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
