Re: How to reduce rail squeal?

["Raj Velayutha" <futuris.velayutha@a1.com.au>]

I met a gentleman in Pueblo(AAR ,US)  who was testing his
'' Invention'' at the AAR for the same reducing wheel squeal and
reduction in Flange/rail life by  a solid  lubricant  Candle.
I am not sure whether he was successful!!
His website:www.kelsan.com
