Built in 1889 by Robert Napier & Sons, Govan, Dora was a single screw ship powered by a triple expansion engine. She was the first LSWR ship to be lit throughout by electricity. Dora had a somewhat short and unhappy career with the LSWR, twice striking rocks in the Channel Islands and, after the second grounding, suffering the ignominy of being towed into St.Peter Port, Guernsey by one of her rivals, the Great Western Railway steamer Lynx. In 1901 she was sold to the Isle of Man Steam Packet Co. and renamed Douglas.
Douglas served with the Isle of Man Steam Packet Co., mostly on the Liverpool - Douglas night service until August 1923 when she sank in the Mersey outside Brunswick Dock after being stuck by another vessel, the Artemisia.
