A cab ride in a freight yard loco but a model one which due to the freight like subject piqued my interest.

The only downside for me are the sound effects especially the engine noise which if played through 12" full range speakers is quite a pleasurable and vaguely authentic experience but when, as I suspect in this case, played through the tiny sounders generally placed in either a loco, tender or van I have to admit to finding them somewhat irritating.
