Transit Bus Fleets
If you have a transit bus fleet, transit stations require special
considerations because they must fuel large numbers of vehicles with high
volumes of fuel in short-fill windows (e.g., 20 to 300 buses requiring 30 to 50
diesel gallon equivalents per day, all within a four- to eight-hour fueling
window). Instead of the traditional fast-fill design, these stations are typically
designed to fuel vehicles directly from the compressors and have lower station
storage capacity. They have multiple large compressors, and buses may be
fueled indoors while being cleaned. Consequently, these stations require
significantly more engineering and are typically more costly than stations
serving other types of fleets.
