There are / have been horse tramways in the following places in Belgium:
Liège is a large city village with (today) almost 200.000 inhabitants. This number of inhabitants was also valid in the years around 1900. Liège is the main capital of the province with the same name and is situated in the eastern part of Belgium.
On 1872-01-20 an English company "Liège Tramways Company Ltd" opened a horse tramway in Liège. It was with rails in normal gauge (1435 mm) running from the station Gare de Guillemins to the Place Saint-Lambert. Later on it was extended to Coronmeuse and Herstal. In 1875 the lines were taken over by a Belgian company, the "Tramways Liégois" (TL). In 1881 a second horse tram line was opened "Société Frédéric Nyst et Cie", on 1898-04-21 obtained by the tramway Est-Ouest Liégois (E-O). In 1882 a new line was opened from Cornillon and Haut-Pré.
On 1899-10-29 the lines of the E-O were replaced by electric trams. When the lines of the TL haven been replaced by electric trams is not known to me.
Unknown to me. One of the open horse tram carriages (number 132) is remained in the museum "Musée des Transports en commun de Wallonie" in Liège
