Speed potential of BOXNHSM1 and BCNAHSM1 wagons with CC+6/CC+8 loading is 90/75 kmph and 100/75 kmph respectively in empty/loaded condition. Speed potential of these wagons with CC+8 loading is 90/60 and 100/60 in empty/loaded condition. Thus, by converting 1 wagons to BOXNHSMSeries /BCNAHSMwagons it would be possible to enhance speed of these stocks to minimum 90 kmph in empty (with CC+6 as well as CC+8 loading) and 75 kmph in loaded (with CC+6 loading). Conversion of all BOXN/BCNA type stock to BOXNHSMSeries /BCNAHSMbesides improving productivity and throughput, shall also bring uniformity in speeds of all variants of BOXN and BCNA wagons which will enhance safety by operational problems/confusions due to multiplicity of speeds. This will also result in standardization of suspension springs/bogie components resulting in better availability and maintenance in comparison to multiple type of components/combinations of springs on bogies of same type of wagons. Conversion of BOXN/BOXNM1/BCNA/BCNAM1 wagons from NLB to NLBHSMtype involves modifications in suspension springs, spigot, bolster etc. Estimated cost of these modifications is about Rs.65000 per wagon. Therefore, provision of Rs.591.5 Cr. against DRF may kindly be made in RSP 2009-10 for the subject work. The conventional air brake system is designed with single brake cylinder mounted on the under frame of the wagon which is connected to the bogies through slack adjuster and linkages. It requires complex brake rigging elements comprising of long pull rods for transmitting the braking forces to the wheels. The conventional system suffers from many defects like hanging of push rod/pull rod, which is a safety hazard and enhanced maintenance requirements. The advance Railways systems have already changed over to bogie mounted brake systems which have one brake cylinder for each bogie with bogie mounted slack adjuster and automatic load sensing device for adjustment of brake forces according to empty/loaded condition of the wagon. Bogie mounted brake system offers following advantages over conventional system, It is lighter and compact system with improved reliability and higher brake rigging Automatic adjustment of slack in rigging system eliminates continuous long periods of brake application before adjustment. Automatic brake force adjustment for empty/loaded condition ensures that manual intervention is not required and consequent damages on account of human error are not In view of the advantages as above, RSRC has also recommended retro fitment of existing stock with bogie-mounted brakes. It is proposed to fit bogie mounted air brake systems on 10,000 Air Bk. Wagons. The cost of retro fitment of bogie mounted brake system is estimated at Rs. 2, 25,000 per wagon. The proposal for retro fitment of 10,000 Air Bk. Wagons with bogie mounted brake system @ Rs. 2, 25,000 per wagon with estimated cost of Rs. 225 Cr. is proposed The total cost of RSP Wagon 2008-09 comes to Rs.5966.21 Crores out of which Rs.167.47 is on Capital account and Rs.5798.74 Crores on DRF account. kind approval of the Rolling Stock Programme (Wagons) for 2009-10 is solicited.
