For general Intermodal terms, see the Intermodal Glossary
A railroad moving a container or providing terminal services as an agent for an EMP participating railroad. Containers in the care or custody of an agent railroad are treated as though they are in the care and custody of an EMP participating railroad.
IMC's can acquire an assignment of units. The purpose of taking units under assignment is so that the units will not be returned empty to the ramp and will constantly be re-loaded and shipped in a high volume lane on the rail. In return, the customer typically receives a lower per diem rate.
A unit that is loaded improperly, mechanically defective, or has safety violations is considered "bad ordered."
Bill Of Lading
A document issued by an IMC to the railroad specifying shipment instructions. Bill of Lading is commonly referred to as "EDI 404," "shipping instructions" or "billing."
Any time that a unit is not under control by a railroad and is under a particular IMC's control.
A biweekly process of invoicing by REZ-1, which is run as follows: Reservations that complete between the 1st and 15th of each month are invoiced around the 17th of the month. Reservations that are complete between the 16th and the end of the month are invoiced around the 3rd of the following month.
A discrepancy, submitted by fax or electronically filed via REZ-1, with any portion of a statement.
A three part series of characters given out by REZ-1 to an IMC who, in turn, will give it to a drayage provider so that they can use it at a ramp to pick up an empty unit for loading and shipment.
- The first four characters indicate the units program and size (ex. EU48. E means EMP. U means standard. 48 means 48 feet long.).
- The next character is the reservation type (ex. G means general).
- The last 5 characters are a series of randomly chosen numbers (ex. 34772).
After a reservation's shipment has been delivered and the reservation has moved into billing by REZ-1, the booking/reservation number can be "recycled" and applied to some future reservation.
Term used to describe an intermodal product for which an allotment of "free days" or relief of per diem is built into the line haul rate. SPDU containers are marketed as a bundled product.

Car Location Message, a railroad generated message that reports the location of moving rail cars, including flatbeds carrying intermodal units.
A large, reusable receptacle that resembles a truck trailer without wheels (chassis), that is lifted on to flatcars. Containers are designed for all modes of intermodal transport, and can accommodate smaller cartons or cases in a single shipment, designed for efficient handling of cargo.
Crossover charges occur when a unit is taken from one ramp and returned to a different railroad in the same, or a different metro area. In specific cities, the railroads may impose crossover charges.
When a unit is moving from one railroad to another, at the point of exchange, it will be trucked from the first railroad's yard, to the second railroad's yard. This time on the road is called "cross-town."

Electronic Data Interchange, the protocol used by companies to send and receive electronic messages concerning container reservations, movements, and invoices.
A domestic interline container service offered by Union Pacific and Norfolk Southern. Also included in the program are agent railroads, such as I&M Rail Link, Iowa Interstate, Wisconsin Central and Kansas City Southern. EMP provides a fleet of nearly 35,000 53' domestic containers and chassis that move throughout a nationwide intermodal network.
A freight car having a floor without any housing or body above. Frequently used to carry containers and/or trailers or oversized/odd-shaped commodities.

Units can have different grade types, such as "food grade," "paper grade," "general grade," etc. All EMP units are general grade.
EMHU's are also called "high cubes." They are 53-feet in length like the EMRUs, but are greater in height, thus allowing greater cubic capacity.
Intermodal Marketing Company. This company is a broker or "middleman" who reserves containers (through REZ-1) for their customers, who are in turn, companies that want to ship truckloads of their goods from manufacturing plants to wholesalers, or from wholesalers to retailers.
Term applied to units arriving at a railroad terminal over the road, from a trucking company.
Ingate Load or Load/Load
Term applied to a unit re-loaded while away from the railroad. A trucker takes the loaded unit from a railroad terminal and unloads its cargo, then loads the same unit with a new shipment and returns the unit to the terminal for further hauling by the railroad.
Interchange of equipment between differing modes of transportation, which include: rail, truck, or ocean.
The written recap of an IMC's reservation from REZ-1, to include, but not limited to, cancellation, expiration, origin and destination dwell times.
A report filled out during the ingate and outgate process. The J-1 details damage to the unit, container information, shipping information, drayman involved and time of ingate/outgate.
The pre-described course a unit follows from origin to destination on the railroad, also known as a valid origin/destination pair. Valid "lanes" are determined by participating railroads.
A lane incentive is applied when a unit ships as a load from a specific origin ramp to a specific destination ramp. (Other restrictions may apply.)
The movement of a unit on the railroad from origin to destination.
Line Haul Rate
The amount charged by the railroad (to an IMC) for a shipment, dependent on the actual origin and destination.
A code assigned to a particular region indicating its location in or near a large city. All EMP ramps have an assigned metro code. Several of them may be included in the same metro code.
A misuse charge is a penalty imposed by the railroads for taking a unit out of one metro area and returning the unit to another metro area empty or loaded. For example, if a unit outgates in Detroit and ingates empty or loaded to Chicago, a misuse charge will occur. These charges are determined by participating railroads and can be changed at any time.
The process whereby the railroad will inform the drayage provider or IMC that a unit is available for pickup. The notify will place the move in a destination dwell status.
A unit is considered off-route when it travels in an invalid lane (such as Las Vegas to Allentown) or when it travels on a non-participatory railroad (such as BNSF Railway). An IMC will be charged off-route charges by REZ-1 until that unit is brought back to a valid terminal.

A rail-truck or truck-rail movement in which Union Pacific has combined the rail and drayage into a single transportation package for EMP and SPDU containers. Containers are shipped via rail from one terminal to another. After that, a contracted drayage firm drays the container to the paper ramp operators lot for customer pickup. The process also works in reverse as well, shipment can originate with the truck movement and then move to the rail portion of the movement. Also referred to as a paper ramp.
A rail-truck or truck-rail movement in which a participating railroad has combined the rail and truck movements into a single transportation package for EMP units. Units are shipped via rail from one terminal to another. After that, a contracted drayage provider trucks the unit to the paper ramp operator's lot for customer pickup. The process also works reverse as well. A shipment can originate with the truck movement and then move to the rail portion of the movement.
Pick-up incentives credit customers when a unit is picked up empty from the specified reservation ramp(s).
Rail User Number
An ID number given to an IMC by REZ-1. An IMC will use this number when they make reservations to prove that they are a valid member of the EMP reservation program.
Slang word for an intermodal terminal. Ramps were originally structures, permanent or temporary, from which trailers or machinery are driven onto or off of a railroad flatcar.
A shipment generated by the railroad for repositioning empty units from one location, to another location in which they can be better utilized or to a location that is deficient.
Term used by REZ-1 to describe a railroad terminal, where an empty unit is picked up with a valid booking/reservation number.
A railroad terminal that a unit is brought back to after dropping off its shipment. This drop off will complete the original move. It will also start a new move if it's brought back with another shipment.
