No reason to accept that.

The only English paper I could find even briefly mentioning a "train track bus" triad in crosscultural context was here, and it describes differences between East and West Europeans, who both tend to make the "thematic" (i.e. train-track) selection over the taxonomic (i.e. train-bus) one, West Europeans more pronounced than East. Beyond the poor theoretical grounds, then, this directly contradicts the BBC exposition on "Eastern" vs. "Western" analogies.

Bad BBC. Bad.
