There are 2 benefits of this idea, first we have a very different train to run and secondly we reduce the types of cars stored in Wellington.
Picking up a caboose in Wellington yard you proceed to the coaling tower and pick up the empty there. Following the high line you stop at Valleyview to pick up another empty at Zorra Cement. Arriving at Springbank you swap out the 2 empties for 6 loaded coal hoppers at the mine. After hooking up your caboose you proceed down through Lincoln and Jutland. You deliver the 6 loads to the power plant and pick up the 6 empties. Run through Herons Landing taking the lower loop by ADM coming out of the tunnel by Oxford Sand and Gravel and go through town again and back up to Springbank. There you drop off the 6 empties picking up the last 2 loads. The mine now has 8 empties to load. One load is dropped off at the cement plant and the other is delivered to the coaling tower in Wellington., dropping off the caboose completes the run.
Note there are no coal hoppers in the Wellington yard. If we want to use empties and loads, they would need to be swapped on Friday or before the next session. We would only need 16 hoppers for this run, we have 28. We could set up 3 branch line trains with 2 coal hoppers requiring 6 more. What do you Think?
