300 bar is probably similar to that run in compressed air locos used in
hazardous environments around factories and in mines. Don't know if they are
still used now diesel and battery locos are available, but they were
certainly a viable alternative to steam locos.
See http://www.internationalsteam.co.uk/trains/fireless01.htm for examples -
essentially a steam loco with compressed air tank instead of boiler.
