It is proposed that six cwt should travel on the Rail-road between this City and Waterford, ten miles an hour, urged by the propelling and locomotive engines. Thus, on the sixth day, the heaviest goods will reach London from Limerick; the fourth, Liverpool; and the third, Bristol.
In case the navigation of the Suir should be found inapplicable, an extension of the Railway to Dunmore is intended.
The undermentioned are expected to form the Committee, some of whom have already signified their intention to that effect:—
The Duke of Devonshire, the Marquis of Lansdowne, Earls Darnley, Glengall, Kenmare, Charleville, Kingston, and Ennismore; Lords Oxmantown and Lismore; Messrs T S Rice MP, J Smith MP, R Wellesley MP, Captain Maberly MP, Sir C Flower, Alderman Heygate &c.
Dublin Evening Post 3 February 1825
Some later information here.
Nowadays, the average duration of the eight daily trains between Limerick and Waterford is four hours and five minutes, for say eighty miles, so speeds have doubled since the 1825 proposals were made.
