The only other discussion for CATBus is over 5 years old and not being used. So I figured I'd start a new one with new information.
In recent years, CATBus has purchased several new Proterra buses as they are on the way to 100% electric buses. I've updated the Wiki with some of that information.
Bus assignments have changed slightly over the recent years as ridership increases and new buses are purchased.
Clemson Area Bus Fleet:
The buses assigned to the Clemson area fleet sport a orange and purple livery except for a few buses which have a purple and silver livery.
100s (2002 Optima Opus 30') - These buses are not used on the city routes often, I'm not sure if they're still used regularly on the campus routes.
200s (2003 Optima Opus 35') - These are also not used regularly on the city routes often and I'm not sure if they're still used regularly on the campus routes.
300s (2004 Optima Opus 35') - These buses are used more often on the campus routes and some of the outlying city routes. However, as the new Proterras enter service, these are usually used more as spares for the city routes.
400s (2012 NovaBus LFS 40') - These buses originally were only used on the Red Route, however they are being deployed on other routes more regularly now.
600s (2012/13 Nova Bus LFSArtic 60') - These buses are still only used on the Red Route during high traffic times.
1800s (2018 Proterra Catalyst BE40') - These buses are used on all city routes. First buses to have white destination signs.
Seneca Area Bus Fleet:
The buses used on Seneca routes are branded differently than the regular fleet, these buses are blue and gold, featuring a slogan: "Powered by Seneca, Driven by CATBus." Originally the local routes operated with 35' buses and the Express between Clemson & Seneca operated with a 40' bus. However, the newest buses are 40' and all the routes are operated with a mix of 35' and 40' units, depending on what's assigned on a particular day.
E-100 - E-104 - (2012/13 Proterra EcoRide BE35) - Typically these buses are rotated out regularly so some aren't used more than others. However, with the purchase of the latest buses, I'm not sure if some of these have been retired or not.
E-105 (2015 Proterra EcoRide BE35) - This bus is in an all white livery, I believe it was a demo unit from Proterra prior to entering the CATBus fleet.
E-106 (2016 Proterra Catalyst BE40) - The first 40' Proterra in the CATBus fleet. This bus originally operated only on the Seneca/Clemson Express route, however with the purchase of the latest buses being 40', this bus is rotated through the other Seneca routes now.
E-106 - E108 (2019/20? Proterra Catalyst BE40) - These buses entered service in November 2019, so I'm not sure if they are 2019 or 2020 models. These buses are rotated throughout the entire Seneca network regularly.
Photos I've gathered over the past few years are below with some other information.
