Single-yard requirements.
A single receiving point still needs a clear delivery plan. Specify the usable storage capacity, normal drawdown, delivery window, and site contact. Describe access, unloading, and appointment requirements so a proposed arrangement can be evaluated against the facility's actual limitations before a commercial commitment is considered.
Multi-location programs.
For a network of yards or service facilities, list each location's demand and receiving conditions. Separate a shared purchasing agreement from the individual delivery needs. Seasonal changes, varying schedules, and different site capacities should be visible in the brief rather than hidden within one aggregate volume.
Transitions and spot needs.
If you are changing suppliers or covering a defined short-term requirement, explain the intended start date and how it relates to your existing arrangements. Identify a firm deadline and any flexibility. Urgency should be stated clearly, but an enquiry does not establish emergency delivery capability or confirmed availability.
Also clarify what you mean by the delivery method. Fuel for locomotives is not automatically fuel delivered by railcar, and delivery to a storage tank is not the same as direct locomotive fueling. State the arrangement you need so responsibilities, access, handling, and the receiving point can be reviewed without assumptions.
