APPLICATIONS
Drivers Cabin
Drivers' comfort is an important aspect to ensure the safe operation of rolling stock networks globally. Sigma's locomotive driver's cab air conditioning systems have been designed to operate in some of the harshest conditions both around the world and in Australia where outside temperatures reach as high as 55°C.
Freight Locomotive
Freight locomotives are normally designed to deliver high starting tractive effort and high sustained power and travel over long distances. Sigma's HVAC solutions provides comfortable internal environment for those long journeys.
Track Maintenance Vehicles
Maintenance of the railway infrastructure is mandatory to provide a safe service. Damage or broken catenary will cause transport interruptions and economical drawbacks. Sigma's track maintenance cab air conditioning systems have been designed to operate in some of the harshest conditions.
Track Range
E-Series
