A practical model has been developed for the assessment of human thermal comfort in
rail carriages. The PMV model is based upon the existing ISO 7730 standard for assessing
moderate thermal environments (PMV: Fanger 1970), with correction factors to
account for the extreme environmental stimuli that may be experienced by some
passengers seated next to windows (i.e. exposure to direct solar radiation or the effects
of a cold window). Three sets of laboratory experiments and four field trials were
conducted. Environmental conditions and mean skin temperature were recorded and
thermal rating questionnaires filled in by participants. [Continues.
