Para 427 of IRPWM deals with measures for reducingwear on outer rails on curves, by lubricating the gaugeface of outer rails. This lubrication is presently done byapplying the graphite grease manually. To save themanpower and consistency of lubrication of track,RDSO has done a trial by procuring 12 Nos. of trackMounted Imported & mechanised lubricators.

After gathering experience from field trial of theselubricators, existing specifications have been revised.Final draft specifications has been sent to RailwayBoard for approval. This specification covers therequirement of lubricating system, properties oflubricant, performance of applicators, control ondispensation of lubricant and performance and travel ofgrease to minimum 2.0 km distance in all climatic &traffic conditions and reduction of coefficient of friction to0.25 µ

Various firmshave expressed interest in reference to EOI issued byRDSO.In order to freeze norms for registration of firms forupgraded AT welding technology, amendments to'Indian Railway Standard specification for fusionwelding of rails by Alumino-thermic process (IRST-19-1994)' and 'Manual for fusion welding of rails byAlumino-thermic process-1998 (Reprinted, 2006)' wereprepared keeping in view the conditions laid down inEOI for enlistment of firms and Railway Board.Accordingly, draft correction slips to IRST-19-1994 andAT welding Manual were sent to Railway Board videletter no. CT/Welding/TDG dt.30.09.09. The issue wasdiscussed at Railway Board and on obtaining RailwayBoard's approval to correction slip, these correctionslips have been issued vide letter no. CT/ATWelding/Sub-Committee.

The quality of AT welding is a matter of serious concern.On number of occasion, zonal railway reports excessiveno. of defective welds in acceptance test. The reasonfor excessive percentage of defective weld is mostly onaccount of poor execution. In order to promote strictquality control during execution stage and analysis ofthe defects at zonal railway level, RDSO had proposed acorrection slip to to 'Indian Railway Standardspecification for fusion welding of rails by Alumino-thermic process ( IRST-19-1994)' and 'Manual for fusionwelding of rails by Alumino-thermic process-1998
