AUSTIN (KXAN) — In an effort to maintain continuity among its fleet, Capital Metro is retiring the last burnt orange and white UT Shuttle bus on Tuesday. The UT Shuttles are being replaced with new blue Capital Metro-branded buses to serve The University of Texas at Austin campus.

After 18 years of service, the agency says it was time to replace the aging buses. The new buses have improved air conditioning systems, HD camera, Braille placards as well as additional turn signals and brake lights.

The new buses will allow for CapMetro maintenance crews to substitute the first available bus without causing any confusion due to the buses color. Now that all Local service will use vehicles of the same color, buses will be interchangeable with a simple switch of the digital destination sign.

While the colors will change, the buses will remain free of charge to UT students, faculty and staff who have active UT ID cards. CapMetro says last year the UT Shuttle provided more than 3.7 million rides.
