To promote this major service improvement, a duplicate 87001 was fabricated. However this full-size replica was made of wood. After being exhibited in the McLellan Galleries in Glasgow, the replica was displayed for some time on a barge on the river Clyde. The exhibit was watched over by a man in a rowing boat, as the barge was considered a hazard to navigation if it detached its moorings. The wooden replica 87001 remained in full view for some time.
