Overview

The Black Canyon Railroad is an interconnecting railroad from Holbrook, Arizona to Kingman, Arizona.
Eastbound operation usually begins in the main yard at Exodus.
Passenger trains first stop at Isaiah Station.
Continuing on from Isaiah, the next stop is Jeremiah.
After departing Jeremiah, the two Express Daily trains meet at Obadiah.
Once the meet is completed, the eastbound passenger train rolls down the hill to Jonah Junction for a flag stop.
Following the Jonah Jct. stop, the last stop is at Alpha, another flag stop.
Departing Alpha, the passenger trains are turned at Black Canyon Yard, by way of Omega and prepared for the return trip.

Westbound passenger trains would, naturally, reverse the previous route.

Freight trains run on a car card envelope/waybill card system.
Each piece of rolling stock has an envelope with the information for that car on the front and a service record on the back.
Each time a car is dispatched into a consist at Exodus or Black Canyon Yard, a waybill card is inserted into the car card envelope.
Each waybill has either three or four stops listed on it.
When the car reaches the destination listed, it is switched into position, the waybill is turned to the next stop, and the car envelope with the waybill still inside it is placed in the “Incoming” portion of that town’s boxes, with the service record side facing out.
Before the next session,the car envelopes with the information side facing out are placed in the “Outgoing” box, the envelopes with the service record facing out are turned so the car information is facing out, and left in the “Incoming” box.
When a car reaches either Black Canyon Yard or Exodus, the waybill cards are removed, returned to the dispatcher, and new cards are assigned at the start of the next session.

The way freights have a lower priority than the passenger trains and therefore must clear the main when a scheduled passenger train is coming through.
At Isaiah and Jeremiah this is usually not a problem, as there is plenty of room for the freights to work while the scheduled trains pass by.
However, in the town of Obadiah the spurs are on both sides of the main and through a cut in the ridge that divides the town; when the Express Daily Passengers meet here the freight is sure to be the target of some good-natured ribbing by the Passenger engineers.
There is only one spur at Jonah Junction, and none at all in Alpha, so the east bound freight consist has little to do once it has left Obadiah.
The westbound freight has a standing special instruction: pick up all Flagstaff freight at Jeremiah and switch it at the Flagstaff cutoff.
Similarly, Jonah Junction freight carried by the westbound consist needs to be parked at the next town (Obadiah) for the eastbound train to pick up and deliver.
