RailMac 35T Lithium Battery Locomotive
The RailMac 35T lithium battery locomotive, with a self-weight of 35 T, adopts lithium battery as power source. Equipped with a Motor Power of 110 KW*2, it also features an Hourly Traction of 80 kN and a Maximum Traction of 92 kN. Lithium batteries have the characteristics of high energy density, high conversion efficiency, no memory effect, no charge-discharge delay, low self-discharge rate, and wide operating temperature range. In particular, lithium iron phosphate batteries have the advantages of non-toxic, non-polluting, good safety performance, long life and wide sources of raw materials, and long life. Its application on locomotives effectively solves the lead-acid battery problems of requiring frequent maintenance, frequent charging and insufficient cruising range in long tunnels.
The company provides customers with comprehensive life cycle services, from design to power system supply, installation and commissioning, to after-sales service, training, and spare parts supply, as well as troubleshooting and overhaul technical support. This full range of services ensures that customer equipment maintains high reliability and long-term operating efficiency during use.
We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from troubleshooting to overhaul technical support.
Advantages of 35T Lithium Battery Locomotive
-
High-capacity Battery and Power: Equipped with a 500Ah battery capacity and 110KW*2 motor power, the 35T locomotive has strong power storage and output capabilities. The hourly traction of 80kN and max traction of 92kN make it suitable for heavy-duty transportation tasks in subway and tunnel shield construction, such as hauling large-scale gantry cranes and shield machine parts.
-
Speed and Efficiency: With an hourly speed of 10km/h and a max speed of 19km/h, it can balance power and speed well. It can transport materials and personnel quickly while ensuring sufficient traction for heavy loads, improving the overall construction efficiency.
-
Reliable Safety Performance: Lithium iron phosphate batteries have good safety performance, and the 35T locomotive is also equipped with multiple safety protection devices, such as overvoltage, under-voltage, and over-current protection. These devices ensure the safe operation of the locomotive in various construction environments, protecting the safety of equipment and personnel.
-
Sustainable and Cost – effective: The use of lithium batteries conforms to the concept of sustainable development. In the long run, due to the long service life and low maintenance cost of lithium batteries, the 35T locomotive can reduce the total cost of construction projects while achieving environmental protection goals.

Railway&Tunnel Construction
RailMac Railway & Tunnel Construction builds railway tunnels to overcome natural/urban limits. Tunnels shorten routes, boost train efficiency, and reduce surface traffic/residential interference (e.g., mountain/urban tunnels). They need detailed geological surveys and advanced tech like the shield method for safety/efficiency.
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.
Track Body Components
RailMac provides railway solutions, focusing on one-stop Lince/Huanji wiper services (R&D, production, maintenance) plus rail air conditioning. It offers diverse wipers (DC110V/74V/24V, pneumatic) and developed China’s first IP-owned CRH3 EMU wiper, with products batch-loaded in CRH380/CR400BF/CR300BF.
Maintenance Equipment
RunWell is a high-tech enterprise specializing in the fields of rail transit and military industry. Its car lift machine products integrate German drive technology (such as the Demag three-in-one modular system) with intelligent control, supporting heavy-duty conditions of over 150 tons.
Railway Components
CRRC specializes in innovative environmental protection sanitation systems. Products like vacuum water - saving toilet modules and waterless ecological toilets, made in an orderly factory, are applied in railways, public facilities, and outdoor scenarios.
RailMac
Partnering with global leaders, RailMac offers superior railway equipment and solutions at competitive prices. It hit milestones like Thailand’s 2017 first local train, pioneered SEA new energy trains, and joined Russia’s high-speed rail project, boosting its railway industry presence.
