RDSO's report no. TFC-77 (January 2002) of the ... - eLocoS

i) Improvement in enginemanship;ii) Availability of working sanding gears;iii) Use of WAG7 (in place of WAGS) as banker;iv) Use of dynamic braking;Rosawhile examining the problem from a technical point of view feels that the earlier loadtables issued were inadequate because they were based on the following conditions:i) Fair weather conditions i.e. dry rail conditions,ii)Tangent track Le. straight track without any curvature,iii) Adhesions values - taken corresponding to standard track conditions,Iiv) Track maintained to standard conditions.Besides this, in case of BaXN wagon loading is permitted up to CC+2 t; therefore load of 58BOXN rake is being considered as 4850 t as against existing 4700 t. Hence revised loadtables have been issued for both diesel and electric locos.The cost implications however, for following the revised load tables will be high. S.E.Railwayvide their letter No. 48/4 dated 7.3.2001 has asked for additional 130 electric and 40 diesellocos for following the existing ROSa load tables. The same may further increase if revisedload tables are used. Average additional loco cost is Rs. 3.75 ~rores and homing sheds forabout 100 locos will cost another Rs. 10 crores.Besides this, we should also take into consideration the cost of strengthening of bridges onthe section, as double-headed operation is not permitted on certain BGML spans. Theapproximate.cost l cti strengtheninQ n~~ 8r.11 pf ~5.7 m BGML girder brid~e as per ROSa'sspecifications has been worked out as Rs. 12.50 lakhs.These additional costs might not commensurate with the advantages gained except inreducing the cases of rail burns (extra cost incurred on Bilaspur division during the last 4 .years in replacing burnt and scabbed rails is rough~ ·Rs. 14:4~Ocrores) a~dincreasing line
