Caio Top Bus 2004 — 25m Biarticulated São Paulo BRT Mod

Caio Top Bus 2004 — 25-Meter Biarticulated São Paulo BRT Trunk-Line Mod for Proton Bus Simulator

The Caio Top Bus 2004 is the 25-meter biarticulated urban bus that became the icon of São Paulo's Expresso Tiradentes BRT corridor — a Brazilian coachbuilder's high-capacity flagship on Volvo B12M chassis, configured for trunk-line mass transit on dedicated municipal lanes. This Proton Bus Simulator mod brings the legendary paulistano biarticulated into PBSU with the two-joint articulation, the Volvo B12M floor-engine driveline, and the unmistakable silhouette that defined Av. Tiradentes corridor operations through the 2000s.

Highlights and Features

• Drive a 25-meter biarticulated urban bus, the largest passenger-capacity rigid-class configuration deployed on São Paulo BRT corridors.
• Operate the two-joint articulation system that distinguishes biarticulated from standard 18-meter articulated buses.
• Master the Volvo B12M floor-engine chassis, the heavy-duty platform that anchored Brazilian BRT trunk-line procurement in the 2000s.
• Deploy on the Map Projeto SP and other BRT-corridor maps with dedicated lanes wide enough for the 25-meter footprint.

Compatibility and Technical Details

About the Real Caio Top Bus 2004

The Caio Top Bus is the high-capacity biarticulated urban bus body family from Caio, the Brazilian coachbuilder headquartered in Botucatu, São Paulo state. The 2004 variant was deployed on São Paulo's Expresso Tiradentes corridor — the city's dedicated BRT trunk line along Avenida Tiradentes connecting the central area to the northern districts — where the 25-meter footprint and two-joint articulation delivered the passenger-throughput volumes that justified the dedicated municipal infrastructure. The Volvo B12M floor-engine chassis was the heavy-duty platform of choice for Brazilian BRT procurement in the 2000s, paired with Brazilian coachbuilders Caio, Marcopolo, and Neobus on biarticulated configurations across São Paulo, Curitiba, and other capital city corridors. The Caio Top Bus 2004 represents one of the iconic Brazilian biarticulated configurations of the era and remains a landmark of paulistano BRT history.
