Breaking the 120 km/h Barrier: Successful Tests of the Karat at the uSky Center
The flagship uBus Karat U4-212 from UST Inc. has reached a speed of 120 km/h during testing at the uSky Test & Certification Center in the UAE.
To achieve this milestone, company specialists developed and installed a traction power supply system integrated into the rail structure. Additionally, the uBus was equipped with a bidirectional converter, essential for direct reactive power control through dynamic braking.
The Chief Designer of the Rapid Transport Complex at uST Inc. Vitaly Lapkovsky, highlighted that during demonstration runs, the Karat U4-212 exhibited exceptional comfort, with ratings ranging from “very good” to “excellent”. This was largely due to its two-stage pneumatic suspension, which ensures a smooth ride comparable to business-class vehicles while significantly reducing noise levels.
Tests also revealed that 120 km/h is not the limit for the flagship uBus. Further trials will help fully unleash the potential of this rail-based unmanned vehicle.
