Dugald Drummond, the Chief Mechanical Engineer of the LSWR built this locomotive to enable him and senior staff to visit all parts of the LSWR system including his frequent commutes from his home at Surbiton to the new locomotive works at Eastleigh.

Drummond died in 1912 and his successor, Robert Urie, rarely used the locomotive, so it was transferred to the service stock, and used to transport members of the Engineer’s Department on inspection tours of Southampton Docks.

It was renumbered 58S in 1924, a year after it had passed into Southern Railway ownership, but was not resurrected until May 1932 when it was briefly used, together a single 6-wheeled carriage, to take parties to view the extension to Southampton Docks, then under construction.

A reply to a blog post dated April 2013 states ‘the coach part of the Bug resides in the back garden of a house in Swanage and can be clearly seen from the trains on the Swanage branch that pass just a few yards from it.’ [2] A model of the inspection saloon is illustrated as follows.
