. This study examines journey to work by train in Sydney and the relationship with urban form, socio-economic and demographic variables by using multiple regression model. Train modal share between area located close to and away from a rail station is compared by using analysis of variance. Results of analyses indicate that the proportion using train between area close to and away from rail station is significantly different. Several urban form variables are related to the proportion using train for work trips. However, when socio-economic factors are included in the analysis, car ownership is the main determinant for the proportion using train whilst urban form variable such as density does not have a significant influence. Although urban form variables are not the most important predictor for rail modal share, urban form does influence the proportion using train in different parts of the metropolitan region. The findings support the use of urban form policies to reduce the dependence on car. A variety of non-urban form factors that affect mode choice are also identified.
