Bus routes come in all shapes and sizes. Short and hilly, long and bumpy or all of the above. The HDX and HDX CNG (Compressed Natural Gas) from from Thomas Built Buses was built to handle them all. Keep the driver comfortable with features like the standard tilt and telescoping steering wheel and optional adjustable pedals, while air conditioning, coach-style seating and heavy-duty shock absorbers make the ride a perfectly pleasant one for up to 90 passengers. Of course, safety is most important to everyone, which is why the HDX meets or exceeds FMVSS. Their unwavering commitment to the needs of every passenger, driver and customer has made Thomas Built a leader for over 90 years.

Decade after decade, Thomas Built Buses has followed one simple philosophy: design and build the kind of bus that we'd want our own children to ride in. It's a simple idea and it works.

Compressed Natural Gas (CNG) is a fossil fuel substitute for gasoline and diesel. It's cleaner. And more environmentally friendly. Based on the design of our original Saf-T-Liner® HDX, Thomas Built launched the Saf-T-Liner HDX CNG nearly 20 years ago. Since then, we've put more than 1,300 CNG buses on the road.
Versatile, customizable, and current emissions-ready.
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.
