did you check the rail alignment?  I had one that after the engine passed over and applied weight to the next track section caused a misalignment.  added ballast and problem was solved.

Thank You to everyone.  This is a help. I think I saw some ESU decoders at an electronics store that sells model train supplies.  Have to get a stock number and see if can match it up.  Also check out ebay GB.  Thanks again

Hello everyone,  I am running a mix of European and American Brands.  My problem is trying to find a sound decoder that sounds like a modern German Whistle.  The whistle sounds I have heard sound like steam generated and rightfully so since they are for steam engines. The electric and some diesel engines here in Germany have a shrill electronic type whistle.  The closest thing I can remember is the NYC subway had a whistle but now it has horns.  Has anyone heard any sound decoders that don't sound like steam whistles? Thank You

Hello Gandy, I am new to this forum and your post was the first I read.  I just want to let you know a long time ago I was told by an instructor that "the only stupid question is the one not asked." so I guess we reserve the right to ask any legitimate questions because of my ignorance they will not be stupid.
