This study investigates the factors responsible for the state of environmental quality in terms of health, hygiene and occupational safety of train stations on Iddo -Agbado Corridor, Lagos-Ogun, Nigeria. A survey research design was adopted as the research design type. The sample frame of 4,122 commuters was estimated while the sample size of 196 commuters was obtained using the Pagoso et al formula. The sampling technique adopted was the purposive sampling technique as the sampling procedure entailed identification of the train stations on the corridor, division of the corridor into senatorial districts, identification of the train stations on the study corridor, selection of train stations from the identified train stations on the corridor, identification of commuters at selected train stations and administration of copies of questionnaire on selected commuters. The descriptive method of data analysis was adopted (frequency tables, cross tables, charts etc) as well as inferential statistical tools (chi square, analysis of variance and factor analysis). The first three factors influencing environmental quality of train stations were cleanliness and hygiene conditions (3.42 C.P.I.), condition of the waiting area (3.37 C.P.I.) and reliability of the rail service (3.36 C.P.I.) using a 5-point Likert scale. The overall commutersâ€™ perception of environmental quality was estimated as 3.02 C.P.I. which suggests that the environmental quality of train stations was moderate. The factor analysis revealed a Kaiser-Meyer-Olkin value of 0.936 with Bartlettâ€™s test significance of 0.000 which exceeds the minimum standard of 0.6. This implies that this statistical tool is suitable for factor analysis. The principal component analysis showed that over 96% of the extraction values were greater than 0.65 and the variable with the highest communality being waiting time (0.88). The results of total variance revealed 5 unconfirmed factors influencing environmental quality and suggested a cumulative percentage of 72.27% with a variance of 3.35%. The investigation recommended improvements in environmental quality of train stations by implementing a sustainable maintenance framework; preparation and execution of beautification plans for the train stations and adjoining areas and conducting a wholistic rail infrastructure rehabilitation survey. The study concluded that commutersâ€™ perception of environmental quality of train stations on Iddo-Agbado corridor, Lagos-Ogun, Nigeria was moderate as commutersâ€™ value-added services, physical attributes, social services and human experience were the factors responsible for the perceived environmental quality of the investigation.
