   Engine No. 188 was the first locomotive of the road that was painted black with gold striping, and attracted much attention by reason of her novel and handsome appearance. Indian red had been previously, and was for a number of years thereafter, the standard color for both passenger and freight engines, and the substitution of black was a decided novelty, which, although not continued, met with general approval. This engine was, with a number of others, captured by the Confederate forces during the Civil War, and was taken to Richmond, where she was considered to be the best of the lot, and was fitted with a walnut cab and called the "Lady Davis." She was doubtless destroyed, as were a number of the other engines. {This last sentence is in error -- the locomotive was returned to the B&O after the war, repaired and put back into service.}
 

   This sketch was made by author Bell in 1866.
