Air system lubricants for Railways

Air equipment in railways comprises systems that generate, treat, and use compressed air for safety-critical and operational functions, including braking, suspension, door operation, and pantograph control. Key components include compressors (piston or screw), dryers, air reservoirs, and control valves, ensuring reliable performance for rolling stock.

Molylub offers a comprehensive range of railway compressor lubricants to cover all of your rolling stock platforms needs, from tramways and light railway vehicles to heavy duty locomotives.

Most railway applications need high-quality air. Painting, for instance, needs high-quality air free of moisture and pulsations that sometimes come from reciprocating compressors. And tank-car pressurization requires air free of moisture and contaminants.

And as mentioned, compressed air systems on trains often operate in a hostile environment, subjected to the elements and temperature extremes.

Pneumatic system oil for Railways

Pneumatic equipment in railways is critical for safety and operation, primarily powering braking systems, train doors, suspensions, and pantograph controls. These systems use compressed air—often supplied by oil-free compressors—to ensure reliability in extreme conditions, featuring components like valves, cylinders, and air springs to manage air pressure and flow

Air equipment in railway lubrication systems is utilized to precisely deliver lubricants, such as grease or oil, to the wheel-rail interface, reducing friction, noise, and wear. These systems typically use compressed air to spray or distribute lubricants via on-board or trackside equipment.

Railway compressor lubrication involves choosing between traditional oil-injected (screw/reciprocating) and modern oil-free technologies to ensure reliable compressed air for braking, doors, and suspension. Oil-injected systems require high-performance synthetic lubricants resistant to moisture and heat, while oil-free systems eliminate oil carryover to reduce maintenance and improve reliability.

• Lubricant Requirements: Railway lubricants must withstand extreme temperature fluctuations, high vibration, and moisture, while offering long life and low maintenance intervals.

• Maintenance: Proper oil levels and filter maintenance in lubricated systems are crucial to preventing component failure and ensuring consistent air supply.
