school busesThe start of a new school year is a great time to talk about school buses.

School districts across the country are switching their fleets to propane-powered buses and reaping great benefits.

Here’s how the switch benefited the Metropolitan School District of Warren Township, in Indianapolis, Indiana, as summarized in a case study by the Propane Education and Research Council.

Faster Starts in Cold Weather

Before the district replaced 11 of its 188 diesel buses with propane autogas buses in November 2015, cold weather was a huge problem. On the frostiest winter days, the diesel fuel would congeal, making starting the buses nearly impossible. The district relied on block heaters and anti-gel liquids to start the buses, but with the propane buses, the need for those was eliminated.

Reduced Maintenance Costs

As a clean-burning fuel, propane eliminates carbon buildup and the maintenance costs associated with it. Warren Township Transportation Director Steve Smith estimated a savings of $1,600 per year on maintenance and fuel costs for each propane bus. In addition, the transition to propane autogas did not require any changes to the district’s existing maintenance facilities.

Happy Drivers

In the full case study, district drivers reported they preferred the propane autogas buses to the diesel buses because they were cleaner, quieter, and easier to operate.
