    Research on environmental ergonomics of train/commuter is very limited. Thus, this study was conducted with aims
    to determine the environmental ergonomic of public transport, whether it is in accordance to indoor air quality
    standard inside women coach cabin train during operations. Although the number of passengers is increasing, some
    claimed that the indoor air quality for the Malaysian commuter train is uncertain, especially at peak times.
    Unsatisfactory feedback from some respondents—especially female passengers—will affect other passengers to
    remain loyal to use this facility as one of the main transportation to reduce the traffic congestion that will be faced
    if using private vehicles. The study conducted during peak hours on the weekends and the trip took exactly two hours
    and covered 18 main stations. The measurement devices placed at the centre of the cabin Komuter using Air Quality
    Meter (AIRFLOW Instrument Model TA465). The main parameters measured were temperature, humidity, and carbon
    dioxide (CO2). This study also counts the number of passengers riding the train. The results showed that the indoor
    air quality (AIQ) level of the morning hour will affect passengers’ health more compared to the evening hour (this is
    due to the CO2 level that has exceeded the safety standard). Morning hour gave higher reading of CO2 (43.8%) and
    relative humidity (17%) compared to evening hour. Evening hours also showed greater temperature at 3%. The
    findings can give awareness to the train company to improve the IAQ by installing a suitable ventilation system and
    can give comfort to the passengers when travelling using Malaysian commuter train.
