Use for shunting aside, was it the Hampton Court branch that for the first months of its existence operated the passenger service using horses for motive power?
Mark
A few passengers services were horse drawn in the past and one (though really a tourist tram) to this day
These first from Wikipedia:
FintonaThe Londonderry and Enniskillen Railway opened the station on 5 June 1853. From 1856, mainline services were withdrawn, and the station was a branch line from Fintona Junction railway station. Most passenger services on this branch line were provided by a horse-drawn tram car.
The short branch to Fintona became famous as the GNR worked it with a horse tram. Since the line's closure, the tram has been preserved at the Ulster Folk and Transport Museum at Cultra, County Down.
Port CarlisleAs a cheap alternative a horse-drawn service was provided in 1856 between Drumburgh and Port Carlisle for a number of years. In 1914 steam power was used and to try to avoid closure, a steam railmotor called 'Flower of Yarrow' was built and this service to Port Carlisle railway station lasted until the branch was closed in 1932.
DouglasThe Douglas Bay Horse Tramway on the Isle of Man runs along the seafront promenade for approximately 1.6 miles (2.6 km), from the southern terminus at the Victoria Pier, adjacent to the Isle of Man Sea Terminal, to Derby Castle station, the southern terminus of the Manx Electric Railway, where the workshops and sheds are located. It is a distinctive tourist attraction. However works have been underway to relay all of the track in 2019 and at present only a third (from the Derby Castle) is usable, with no published completion date for the works.

History of YorkFor the first few months a steam tram was trialled, but soon horses were pulling the trams. The line was extended through Tower Street, Clifford Street, Ouse Bridge and Micklegate to the Mount by 1882, with a branch along Rougier Street to connect with the new railway station.
Micklegate is a fairly steep incline and an extra horse was needed to pull up the hill. A horse called Dobbin did the job for many years, waiting at the bottom of the hill until the next tram came along. He would be hooked up, do his work and then be released to make his own way back down to his position outside the Post Office.
