The transport cost weights for rail and river transport are currently set at fraction of 0.5 and 0.1 of overland transport. Transport by train and river is thus cheaper then overland transport by a factor 2 and 10 respectively. Now consider a large-scale investment in upgrading the existing rail tracks leading to an increased transport-capacity and reduced transport costs. Click on the Design label. train 0,1 to reflect this decrease in train transport prices. Please note that it may be necessary to enter this value with a comma () sign instead of the original dot (), to prevent it will also be necessary to change the river weight value from 0.1 to 0,1 , in Options ->Weightings, change the transport cost setting to annoying "invalid floating point" message. In that case
