Brazil's Skyrail: A promising project beset by delays.

By EVWorld.com Si Editorial Team

BYD, the Chinese electric vehicle juggernaut, has rarely stumbled in its global expansion. But its SkyRail project—a sleek, elevated monorail system designed to revolutionize urban transit—now stands as a cautionary tale about the limits of exporting infrastructure innovation.

What Is SkyRail?

SkyRail is BYD's proprietary straddle-beam monorail system, developed over five years with an investment of RMB 5 billion and a team of 1,000 engineers. It was designed to carry 10,000–30,000 passengers per hour, navigate tight curves and steep grades, and cost just one-fifth of a subway system with significantly shorter build times.

The Brazil Deployment

BYD’s most prominent international SkyRail venture was in Salvador, Brazil. The VLT do Subúrbio project aimed to build a 23.3 km elevated line with 26 stations, replacing aging suburban rail and connecting underserved coastal communities. Phase I would span 19.2 km; Phase II, 4.08 km. Despite initial enthusiasm and ceremonial rollouts, construction stalled amid funding delays and labor rights violations at BYD’s nearby EV plant. As of late 2024, the system remains incomplete.

Public and Financial Response

Local officials praised SkyRail’s modernity and flood-resilient design, but public engagement has been limited. Citizen skepticism has grown due to delays and lack of visible progress. Financial viability is uncertain, with challenges in securing sustained funding and meeting environmental and social standards set by IDB Invest.

Pilot Programs in China

BYD ran pilot SkyRail programs in Shenzhen, Yinchuan, and Guiyang. These demonstration lines showcased technical capabilities but failed to scale into full deployments. Integration into existing transit ecosystems and long-term ridership remain key hurdles.

Comparison to BRT and Electric Trolleys

Compared to Bus Rapid Transit (BRT) systems, SkyRail offers a cleaner, quieter ride with less street-level disruption. However, BRTs are far cheaper, faster to deploy, and more flexible—making them attractive to cities like Bogotá and Istanbul. Meanwhile, modern electric trolley systems, such as the one recently expanded in Ukraine, leverage existing infrastructure and offer low-emission, reliable service with strong community acceptance.

Conclusion

SkyRail reflects BYD’s bold ambition to redefine urban mobility, but its Brazil venture underscores the difficulty of exporting infrastructure innovation. Unlike EVs, which can be sold directly to consumers, public transit systems require deep coordination with governments, long-term financing, and cultural alignment. For cities, the best transit solutions may not be the flashiest, but the ones that fit seamlessly into the urban fabric.
