The Kingscourt branch line of the rail network was used to transport gypsum to Limerick from the cement factory, but the revenue return from the volume of gypsum on offer by rail was insufficient to cover the rising costs associated with the investment required in the operation and the customer was certainly not prepared to pay the associated higher costs. Unfortunately, that was the only such service on the line. We should examine this point when targeting other industries which operate close to existing rail lines.
