Update: according do Des Kiely a local author in Wexford, the siding was built one year after the cement works opened, circa 1884. The narrow guage works railway was horse drawn and had three spurs joined to a turn table. The company shipped line and cement made with limestone instead of chalk also using the mud from the local estuary.
A major dispute between the Dublin, Wicklow & Wexford Railway and the Waterford & Wexford Railway erupted in May 1889. Services were threatened to be suspended if the W&WR did not guarantee to make immediate payments of monies owed to the DW&WR. At a meeting in the Town Hall in Wexford, the W&WR asked that the service be kept open at least during the bathing season but the line was duly closed. It remained so for the next five years.
With the loss of the important train service into Wexford, Harry Cooper came up with a solution. He built his own steam engine to run on the railway line between Drinagh and Wexford, calling his invention the ‘Puffing Billy’.
It had a boiler and a tall chimney, and ran on four wheels. It became known as the ‘Donkey Engine.’
