The modifications to this locomotive were designed by Dr. P. Le Seur who had previously assisted David Wardale with the design and testing of #3450. The modifications were intended to provide increased performance without being as extensive as those applied to the Red Devil. #3454 features dual exhaust stacks, placed transversely in the smokebox, as clearly shown in this photo.
