 At grouping 196 steam locomotives including the L & MV and Caldon Low engines were absorbed into the LMS along with the three railmotors and one battery electric locomotive . This last engine was built at Stoke in 1917 for shunting the copper works at <unk> . Four engines under construction at Stoke in 1923 were completed and also added to the LMS stock . Although many of the locomotives were not old , due to the LMS policy of standardisation all NSR engines had been withdrawn from service by 1939 . The one exception was the battery electric shunting locomotive which remained in service until 1963 .
