Those locos used in The Ghost and the Darkness belong to the museum where I volunteer. The loco with the bench in the front is a "Kitson" tank loco affectionately known as Kitty and she is the oldest loco in Africa- well over 120 years old. Used to be owned by ESKOM- South African Electricity supplier to South Africa and a few neiboughring countries. Also the othe loco is a Class 6A- also over 100 years old, still in use by the museum. As a matter of interest, besides a lot of films showing or featuring trains a lot of American films/ TV shows feature a train blowing it's horn in the distance.
