Single Line bronze Key Token ROSE STREET - CLACHNAHARRY No 28 (configuration B?) Ex Highland Railway between Inverness and the Far North of Scotland and Kyle of Lochalsh. Dating from 1986, the Token was introduced when BR intended to replace the ageing Tyers No 6 tablet instruments with refurbished electric key token machines. Before this could be introduced, the RETB system came into use and the tokens weren't actually used. As a result, it is in excellent, unused condition.
