Upper Douglas Tramway
Photographs depicting staff of the Upper Douglas Tramway - either under the auspices of the Isle of Man Tramways and Electric Power Co Ltd (1896 to 1902) or Douglas Corporation (1902 to 1929) - are extremely rare. Those that have survived only show drivers and conductors at a distance, and though they hint that a uniform and cap may have been worn, the images are far from conclusive. Whatever the situation prioi to 1902, it does at least seem likely that in Corporation days, staff would have issued with the same uniforms as their colleagues working the horse trams (see link); however, until such time as new photographic evidence comes to light, this remains a supposition.
