Trolley Locomotive
RailMac Trolley Locomotive is a type of railway locomotive that draws power from overhead contact lines. It obtains electrical energy through a pantograph or current collector and drives the electric traction motors. These locomotives are commonly used on electrified railway lines, including urban rail transit (like subways and light rail) and mainline railways. Since their power comes from an external electric grid, they have strong tractive effort and high operating speeds.
Advantages of Trolley Locomotive
Trolley Locomotives have the advantages of high tractive effort, fast operating speed, low noise, and low maintenance costs. They do not need to carry large energy storage devices since they are powered by an external electric grid, resulting in higher operating efficiency.
RailMac 30T Trolley Locomotive
The 30T Trolley Locomotive features a welded – steel frame suspended by leaf springs or rubber studs on grease – bearing seats. It uses an electronic speed controller, with AC converters transforming trolley – line DC to AC to drive 3 – phase brushless AC motors (85kW×2 or 110kW×2).
Tourist Train
The CRRC Zhuzhou 1435 series dual rail sightseeing car inherits the technological DNA of CRRC high-speed rail and is designed for in-depth sightseeing in scenic areas. The innovative double-decker structure features a panoramic window on the first floor for comfortable all-weather sightseeing and an open-top layout on the second floor for a 360° immersive natural experience.
Traction System
CHSR's CHSR™ CC750 air-cooled converter is a highly integrated traction and auxiliary "two-in-one" core equipment. It condenses key power conversion functions into a single compact enclosure, providing robust and stable power for intercity trains through standardized modular design, intelligent air cooling (IP65 protection), and mature and reliable components.
Bogie and Braking System
CRRC Braking Systems Co., Ltd.'s disc brake calipers use hydraulic or pneumatic-hydraulic conversion drive technology.They integrate automatic gap adjustment, modular caliper body, and three-point floating suspension design to ensure precise contact between brake pads and discs.
