The Pacific & American Railroad is a western road that runs from San Bernardino on the southern terminus northwards to a connection with GL&A at King's Gate. The Pacific & American Railroad also has westbound connections to vNERR’s Death Valley & Western at Barstow, vNERR’s Cascade & Northwestern at Whitefish and vNERR's Bison Rail at Clinton.

To facilitate operations the Pacific & American Railroad has been divided into four divisions, and one future division::

• Kings Gate Division

The Pacific & American Railroad uses a combination of payware and freeware routes, purchased from 3DTrainStuff, 3DTrains, Maple Leaf Tracks, and Streamlines.

Whitefish, Hoodoo Pass, North Coast Railroad and Clinton Sub are freeware routes whose authors have generously allowed us to make them available for download here.

When you are accepted as an engineer here at the Pacific & American Railroad you will be asked to pick the Subdivision to which you would like to be assigned. Each Subdivision will have a dedicated call board listing all assigned personnel. You are free to request a transfer to another Subdivision at any time after completing your probation period. Please Note: We will not be changing you on a whim. A good reason will be required.

Each Division is made up of two or three Subdivisions. You may run intra-divisional work orders that take you to the other Subdivision within your Division. You may also run inter-divisional work orders that take you to another Division and on to other Subdivisions. Until you complete a work order that returns you to your home division you will be listed on Temporarily Assigned Duty (TAD). The Crew Callboard will keep track of your current location based on the last time slip that you filed. Simply speaking, your Home Subdivision is your starting point, your favorite route, your favorite area, a personal preference.

Divisions and Subdivisions are used to retain the real world flavor of our operation. By assigning engineers a Home Subdivision we hope that they will develop a Divisional Pride that will motivate them in inter-divisional challenges and competitions.
