66743 GBRT TONB11&12 TONB11&12 D N

GB Railfreight's class 66/7 (JT42CWR) number 66743 . Here it is photographed hauling empty gypsum containers mounted on flat wagons from Mountfield Sidings (GBRf) East Sussex to Doncaster Down Decoy (4E19) on 12 November 2014. To comply with gas emission regulations limestone (CaCO3) delivered to the power station (by other trains) is used to remove sulfur dioxide (SO2) from the flue gasses, by converting it into gypsum (CaSO4·2H2O). The waste product (gypsum) is then delivered to British Gypsum's Robertsbridge Works by train where it is used to manufacture plaster and plasterboard.
