A lot of train guys seem to either really like or dislike a steam engine they purchase or see run depending on what whistle they have. There seems to be a need for a happy medium of a whistle being prototypically accurate while also being pleasant to the ear - including myself. In my experience so far with running O gauge trains and hearing many sound systems, I have thought of which engines have the overall best sounding whistles:
1) Lionel 2012 Legacy Southern Crescent
2) Lionel 1999 Union Pacific Big Boy
3) Lionel 1999 Chesapeake & Ohio Allegheny
4) Lionel 2000 Century Club 773 Hudson
5) MTH's 2002 ProtoSound 2.0 Berkshires
6) MTH's 2001 ProtoSound 2.0 RailKing 0-8-0 Switchers
7) Lionel 2008 Legacy Pere Marquette Berkshire 1225
8) Lionel 2010 Vision Line 700E Hudson
9) Lionel 1999 Denver & Rio Grande Mikado
10) ALL of Lionel's Commodore Vanderbilts
BUT I must know if anyone else has personal favorite hooters~
