High Speed, Rolling Stock and Infrastructure requirements for 2014 at RDSO. This was organised jointly by RDSO and IR Technical experts from Indian Industries and also from Confederation of Indian Industries (CII). As many as 54 foreign industries deliberated their expert views in the Industries from India and abroad participated in this 3 days conference. The conference was very successful and was exhibition. Industries from more than 11 countries like France, widely appreciated in the media and by the Industry.China and Ukraine etc. participated in this exhibition along

with other leading industries from India. Regular technical

Noise Level Measurement of Diesel LocomotiveCRB has desired to reduce noise level in the driver's cab of

HHP locomotive. In preliminary phase, Motive Power Directorte of RDSO has measured noise level in stationary and running conditions and different locations to make a data bank. Max. reading observed in the loco cab is 99 DBA during run of Train No. 12229, LKO-DLI Mail with WDP4D locomotive No. 40124. Noise level data recorded is drafted in the form of a report bearing no. MP.Misc-305 (Rev-00) January-2015. Further, action plan for reducing noise level in cab has been made with DLW. DLW is going to implement some

make driver's cab crew friendly, increasing comfort and modifications in 20 locos in the starting. RDSO is also entering reducing fatigue hours. This will also make the cab in to a technical consultancy with IIT/KGP to work upon noise environment friendly by reducing noise emissions.related issues of locomotive. All these efforts will enable to

failed on line of Loco no 12705 (SBI) as shown in figure. RDSO tensile stress at failure zone. Therefore, it is concluded that it is studied the problem and not a design developed a 3D solid problem and it model of carbody traction may due to rod. FEA is carried out improper welding with the applicable radius etc. Needle maximum tractive force peen finished (2G Load case) at car w e l d m a y body traction rod. It is improve the weld observed that the stress quality as per the found in concerned area requirement of the is very less as compared EMD drawing no.40122500 (CARBODY ROD ASM).

Design of Wider Sleeper Using More Concrete & Less Steel for 25t Axle Load

Inspection of Bhanwartonk DN Tunnel Between Khodri-Khongsara Station of Bilaspur-Katni Section, South East Central Railway

Wide sleeper using more concrete & less steel is being Initial Testing and trials of concrete sleeper with top rail developed by RDSO to increase width and weight providing seat width of 230mm (against existing 150mm) and 300 mm higher frame resistance against buckling, chances of reducing bottom width (against 250mm in existing sleeper)and 12 de-stressing temperature with likely reduction in rail/weld wires(against 20 wires) have been carried out. Based on the failures and to increase rail seat area results in higher rubber pad testing results and analysis done thereafter new designs with the life. Wide sleeper will have reduced ballast pressure leading to same dimensions but with 14 wires now are being developed. reduction in ballast pulverization, deep screening cycle & Once these are developed then they will cater upto 25T axle
