approach road would otherwise have needed to have been. This was to accommodate the Queen's carriages and entourage. Slough High Street was originally part of the Great West Road, which has now been diverted via Wellington Street, allowing the High Street to be largely pedestrianised. Thus Mackenzie Street became a cul-de-sac in 1970 when Wellington Street was redeveloped, and is now part of the Queensmere Shopping Centre. The remainder of Mackenzie Street, north of the redeveloped Wellington Street, was (along with Station Approach) renamed Brunel Way. Opposite the railway station once stood the equally grand Royal Hotel (now demolished). On 1 January 1845, John Tawell, who had recently returned from Australia, murdered his lover, Sarah Hart, at Salt Hill in Slough by giving her a glass of stout poisoned with cyanide of potash. With various officials in chase, Tawell fled to Slough Station and boarded a train to Paddington.
