T&GN/NT&O Train Symbols - Yard Jobs

T&GN/NT&O Symbol Methodology

Yard Jobs

The Car Load Business Unit (CLBU) compliments the Manifest Business Unit (MBU).  Cars not in unit train, cycle train, or intermodal service fall under the jurisdiction of the CLBU between the "first and last mile" from and to the shipper and the receiver and the points of classification.  Between points of classification and/or interchange locations the cars are owned by the MBU.

There are three types of trains in the CLBU: Locals, Roadswitchers, and Yard Jobs.  This page will focus on the Yard Jobs.  Though the concept of a yard job is somewhat self explanatory, there are several specific qualities that yard jobs have.  In addition, there are different types of yard jobs.  Understanding these details will help you to understand the symbol methodology used to identify specific yard jobs on the T&GN/NT&O Railroads.

Generally yard jobs spend most of their time on tracks that are not dispatcher-controlled main tracks.  Some may need an occasional "poke" out of a yard to handle a long cut of cars.  Industry yard jobs may spend more time on the main line to service customers near a terminal.  Yard Job symbols are given the lowest priority, thus they begin with the number "1".  Of course it is possible that a yard job will be handling a high-priority move, such as delivering "shut-down" cars to a customer or finishing an intermodal train.  In these instances terminal management will communicate with the dispatching team about the elevated importance of a specific move.

Yard Jobs go on duty and tie up at the same location.  Therefore in the symbol there is only one  location code--the station where the job works.  The space in the train symbol normally occupied by the origin station code is replaced with a two-number code.  To understand this we will need to discuss a little more detail on how yard jobs work.

Yard jobs are bulletined as eight-hour assignments broken up into three shifts.  First shift yard jobs can go on duty at any time in the 90-minute period between 0600 and 0729.  Second Shift Yard Jobs go on duty between 1400 and 1529.  Third Shift Yard Jobs go on duty between 2200 and 2329.  Larger terminals that process a high volume of cars may have a full compliment of yard jobs on all three shifts.  Smaller terminals will have fewer jobs and may have one or two shifts where no yard job is on duty.  It is the job of local management to determine the needs of each terminal and post jobs accordingly.

The most common function of a yard job is to take apart inbound trains or set-outs and build outbound trains or fills.  Outbound trains can include cars for local industries to be spotted by a yard job.  There are two types of yards that perform this work: flat yards and hump yards.  In a flat yard the primary yard job is called a "lead job" basically working the switching lead to process cars.  Hump yards are larger and process a high volume of cars.  Instead of having lead jobs, the jobs in a hump yard are classified as a "Hump Job" or a "Trim Job"  Hump jobs have one purpose--to fill the bowl with cars.  Trim jobs pull cars out of the bowl and build outbound trains.

Some locations may have yard jobs that specifically work intermodal ramps, spotting and pulling cars, positioning cars from the ramp to be picked up by a train, or even handling the setouts and pickups of through trains.

Industry jobs spot and pull cars to and from industries that are located close to a terminal.  Some industry jobs may have to dig out their cars from inventory in the yard at the beginning of the shift.  Other industry jobs may have their cars to spot made ready to go by another yard job.

Hostler/Pilot crews are yard jobs bulletined at a lower rate of pay which only move locomotives.  Hostler/Pilot crews cannot move cars. These crews are often found in terminals with a diesel facility where a number of through trains are setting out locomotives to be shopped or picking up locomotives that have been released by the shop.  In addition they will take inbound locomotive consists from inbound terminating trains to the shop and take outbound fresh locomotive consists to outbound originating trains. 

Transfer Jobs are yard jobs that are specifically used to interchange cars to and from foreign line railroads in a terminal.  They can also be used to set out bad orders on outbound home road trains and shuttle home road trains into and out of a terminal.

The above information gives us the background necessary to further discuss the T&GN/NT&O Yard Job Symbols.  The fourth character which is found after the station code will generally be a 1, 2, or 3.  This number denotes the shift, 1 being a First Shift job, 2, being a Second Shift job, and 3 being a Third Shift job.  If any category of yard job requires more crews than can be accommodated with the 1, 2, or 3 symbols, then they roll to 4, 5, and 6 with 4 being additional 1st shift jobs, 5 being additional 2nd shift jobs, and 6 being additional third shift jobs.  The number 7 is not used.  An 8 will be used to designate an assigned Transfer yard Job.  A 9 will be used to designate an "Extra" or non-bulletined job called on an as-needed basis.

The fifth character functions differently for several types of the above jobs.  If the preceding digit is a 1, 2, 3, 4, 5,or 6 then the fifth character defines the type of yard job as follows:

​- 0 - Hump Job
- 1 - 1st Lead or Trim Job
- 2 - 2nd Lead or Trim Job
- 3 - 3rd Lead or Trim Job
- 4 - 1st Industry Job
​- 5 - 2nd Industry Job
- 6 - Intermodal Ramp Job
- 7 - 1st Hostler/Pilot
- 8 - 2nd Hostler/Pilot
- 9 - 3rd Hostler/Pilot
If the preceding digit is an 8 or a 9 denoting a transfer or an extra, then the 5th character is a sequential count of that type of job for the calendar day.

All yard job symbols end with the letter Y indicating that this train is a yard job.

Below is the base yard job symbol for each station that has yard jobs.  For the purpose of the below symbol table, only the "11" job or 1st shift Lead or Trim job will be given.  At the bottom of this page will be several examples of specific yard jobs to help clarify the symbol methodology employed for yard jobs on the T&GN/NT&O Railroads.
