Bolton Horse Tramways
In common with the majority of horse tramways in the UK, drivers and conductors simply wore informal but smart attire - trousers, jacket, waistcoat, shirt and tie, and a bowler hat. The wearing of the latter - as opposed to another type of hat - was probably company policy, as staff in all three photos below have them, along with a round, shiny badge, presumably issued by the operator, Edmund Holden and Company.
The second photo also shows an individual who is in all likelihood an inspector; if true, this indicates that smart, single-breasted jackets with upright collars were issued, with the latter appearing to carry some kind of designation, most probably either the employee grade (i.e. 'Inspector') or the company's initials. A kepi-style cap was worn, which carried a badge of unknown pattern, but seemingly different to that worn by tramcar staff; one explanation for this may be that the inspectors were actually employees of the system owners (Bolton Corporation and various local authorities) rather than the lessees.
My thanks go to Ted Gray for high resolution copies of the first two photos below, which were first published in his book 'Manchester Road & Rail' (Sutton, 1996).
Conductor Teddy Whittle and driver (Bob ?) with a three-horse car (F5; Farnworth Depot) in Manchester Rd on the Farnsworth route - photo undated, but from the style of headwear, probably between the mid 1880s and mid 1890s. Both men are smartly but informally attired, with tall bowler hats and a conspicuous round hat badge. Photo courtesy of Ted Gray.
Driver, conductor and inspector (probably) pose with Horsecar B5 on a Bolton-Dunscar service on Blackburn Rd at its junction with Belmont Rd - photo undated, but probably taken in the late 1890s. The inspector is wearing a kepi-style cap, and a badge that appears to be different to the round badge worn by the tramcar staff. Photo courtesy of Ted Gray.
Conductor and driver pose with Horsecar B8 on the Bolton-Dunscar route at the Gatehouse - photo undated, but probably taken in the mid-to-late 1890s. Photo courtesy of the Tramways and Light Railway Society, with particular thanks to David Voice.
