In 2005 I was lucky enough to have recorded the class 442's operating from Bournemouth to Brockenhurst.
These recordings captured many characteristics required for a OO scale model using ESU LokSound technology.
Including:
The whining characteristics of the ex 4-REP traction motors,
Door operating and warning bleepers.
Air Conditioning and Air Compressors.
etc...
However, I have no recordings for Air Horns used on the class 442.
Q: Can anybody advise whether the Cl442 air horns are used by any other train type?
Q: Does anybody have any good sound recordings of the 442's?
