When it comes to our schools, every efficiency counts. That's why we've built so many into our updated Saf-T-Liner® EFX. Seating for up to 90 passengers and a wider loading aisle make this bus ready for whatever the school year brings. The cockpit is designed for driver comfort and safety with ample legroom and optimized access to controls. Plus, our engine cover allows for quick, easy and tool-free access to the engine, fluids and belts, keeping routine maintenance time to a minimum. The Saf-T-Liner® EFX is a front-engine, transit-style bus that is versatile and an excellent value. At Thomas Built we listen to our drivers, mechanics and customers to help us develop the best buses on the road. And with one of the most extensive dealer networks in the industry, there's always support nearby when you need it.
