Mortality rates for leukaemia and brain tumour of highly exposed train drivers (21 \u03bcT average annual exposure) were compared with medium and low exposed occupational groups (i.e. station masters with an average exposure of 1 \u03bcT). In addition, individual cumulative exposure was calculated from on-site measurements and modelling of past exposures.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold>The hazard ratio (HR) for leukaemia mortality of train drivers was 1.43 (95% CI 0.74 to 2.77) compared with station masters. For myeloid leukaemia the HR of train drivers was 4.74 (95% CI 1.04 to 21.60) and for Hodgkin\u2019s disease 3.29 (95% CI 0.69 to 15.63).
