Based on the Arranged Freight Services document, the above graphic illustrates the flow of freight traffic in and out of Lewistown via various train symbols.
This does not reflect cars moving around through locals. Rather, just the routes and trains that carry cars in and out of the Lewistown operating scenario per waybills.
It is interesting to note that less than half a train per day is exchanged with Enola. There is actually more -- a full train -- exchanged with Northumberland! Altoona provides the greatest interchange, with a dedicated train per day plus as much as a third of another.
