This paper mainly deals with corrosion that occurs in under frame of Indian railway coaches, causes of corrosion, steps taken to prevent corrosion, suggestions to minimize this problem. The paper contains new suggestions to mitigate the problem; more emphasis has been laid on welding and anodizing which are being done perfunctorily, the various pros and cons of using aluminum instead of stainless steel for under frame has been explicated.  Although corrosion cannot be mitigated with NDT (non-destructive testing) sampling can be done before installation. The importance of pitting resistance equivalent number is conveyed. Welding distortion that occurs when aluminum is used has been composed. Also residual stresses that occur as a consequence of welding have been adumbrated. The corrosion behavior of silica hybrid coatings produced from basic catalyzed sols by dipping and electrophoretic deposition (EPD) onto stainless steel AISI 304 has been explicated. Importance of surface preparation and surface modifications has been silhouetted. The ground work was done by me in a public sector undertaking in India. .
