(C) General Notes

This sound recording courtesy of Watercress Heritage Railway, UK. .
All sounds recorded by AJ Ireland at Watercress Heritage Line, June 2007.

Each engine we have recorded has a distinct 'personality', so a particular locomotive example may sound slightly different
due to unique e.g. tappet, crank-rate shell vibrations and exhaust-stack, chuff differences. Horns and bells are often moved between locomotives, and
some roads may change/upgrade prime-movers, or change a normally aspirated engine with turbo-chargers etc.
