Why is STA getting double deckers?

The double-decker buses are a key component of the Cheney High Performance Transit (HPT) corridor identified in the STA Moving Forward strategic plan, for which voters approved funding in 2016. The plan calls for enhanced buses and more capacity on the corridor to meet growing mobility needs on the West Plains. Planning work that was conducted between 2019 and 2020 evaluated “enhanced bus” options and singled out the double-decker bus option as preferred.

Don’t articulated buses work well enough for these routes? Why the higher capacity?

Articulated (artics) buses have been effective, but Routes 6 and 66 often experience standing-room-only conditions during peak hours, even on the artics. Double-decker buses provide higher capacity, ensuring a better experience and meeting increasing ridership demand without adding more buses.

What is their seating and total capacity?

Each bus seats 82 passengers and can carry up to 108 riders, including space for two wheelchairs.

How many double-decker buses will STA have?

STA will have seven double-decker buses. The first two arrived in December 2024, and five more are expected in February 2025.

What is their manufacturer, and where else are these buses used?

The buses are manufactured by Alexander Dennis and are the Enviro500 model, the world’s best-selling three-axle double-decker bus. These buses operate in major cities such as New York, Hong Kong, and Dublin.

What routes will they go on?

The double-decker buses will serve Routes 6 and 66, connecting Spokane and Cheney.

Why will the double deckers not be put into service until September rather than sooner?

There are multiple steps that need to occur before the new buses can be put into service. Firstly, the double decker buses have not all arrived yet. After arrival and post-delivery inspection, licensing and registration need to be completed, and essential electronics such as security cameras, fare boxes, and validators must be installed. Mechanics require specialized training to ensure proper maintenance and servicing, and drivers will undergo training to operate the vehicles safely. Thorough testing is necessary to ensure smooth integration into STA operations.

What other features do they have?

The buses are fully ADA-compliant, with space for two wheelchairs, and are equipped with a powered ramp at the front door for accessibility.

Each seat has overhead LED “reading lamp” lighting, like an airplane, and a stop request button.

The buses are also equipped with digital monitors.

Where will they be stored?

The buses will be stored in the Boone Northwest Garage, which was built with taller doors in anticipation of the double deckers. The Boone South Garage has also been updated for maintenance.

Are the vehicles diesel or electric?

These double deckers are diesel vehicles. STA is actively working towards the full electrification of its fleet by 2045. More details on the zero-emission fleet transition may be found here.

How do they handle the snow?

The buses are designed to operate well in snowy conditions. The Enviro500 has a proven track record of working reliably and efficiently across the world in vastly different climates and temperatures, such as in both Canada and Nevada.

But most importantly, will they get stuck under a viaduct or overpass?

No, Routes 6 and 66 were adjusted in 2021 to use the Jefferson viaduct, which has a clearance of over 14 feet, ensuring safe passage for the double-decker buses, which are only 13 feet and 6 inches tall.
