Data from Titre Exposition universelle internationale de 1878 a Paris. Rapports du jury internationale..Volume Groupe VI - Classe 64. Rapport sur le materiel des chemins de fer. p. 56 (cnum.cnam.fr/CGI/fpage.cgi?8XAE277-11.1/54/100/312/0/0 (accessed 1 September 2005) table. The gauge is given as 1.15 m (1015 mm).
This was the winning competitor for a tramway competition in 1877. Some entered service in Glasgow, others in Paris on 15 Sept 1877. The website for the Museum of Urban Transport -- [], accessed 21 Jan 2005) -- notes that the vertical-boilered Hughes was withdrawn in 1878.
A few years later Henry Hughes lost control of his company, which was taken over by Falcon Engine Works.
