Installed two more turnouts and completed the west Proviso loco yard throat. The throat provides four six engine tracks total. Five of the tracks will lead into the Proviso engine house. The sixth track, the one off by itself next to the tanker, will be on outside fueling track. I have just eight more turnouts to complete (105 done so far).
I'm really looking forward to starting some scenery this summer once I get all the trackwork complete.
Here's the prototype fueling track
