I wonder if this is a reality. Imagine having the wonderful smells of steam locomotives issuing forth from your PC. But then we would also have to smell diesel locos! And what about the wagons? Coal, cement and all sorts of chemicals. And of course there a cattle trucks, fish trains and garbage carriers! It will certainly add extra interest to running MSTS. I guess that we will need a new UKTS forum, "MSTS Smells".New Sensation for Microsoft Train Simulator
The latest train simming news is that a major producer of control hardware for Microsoft Train Simulator is about to release a new product, SmellDriver. Apparently SmellDriver will connect to a USB port and provide smells synchronized with what is happening on the route being driven. New entries in the sound files will trigger SmellDriver to release small spays of "odour" from rechargeable cylinders which are housed in the unit. Just think of the possibilities. Smell the diesel engine or the steam escaping from a steam locomotive. Smell the contents of the wagons making up the train. The possibilities are limitless! No information is available yet on the cost.
