May i call your kind attention to rdso' letter no . EL/3.1.3.5/2 DATED 7.7.2005 TEC CIRCULAR NO. ELRS/TC/0083(REV.0) Subjected : limits for wheel set dimension variations and wheel wear of WAP5,6&9 WHERE IN permissible service limit is 1.5mm, in same axle, 4 mm on same bogie and 20 mm on same loco. That Sir I m thankful for your valuable and timely comments. Now two days back I had an accident reference where in the difference on same wagon is reported to be 34 mm. So shall we go by there is no limit in service. Pl do send me your most valuable comments. Same logic applies to disel. For coaching also it's 1.6 mm circumference difference on ICF. 🙏🙏🙏🙏
@@yourderailmentguide8902 Sir the difference of 0.5mm is during turning as there has to be some tolerance.but you say one the difference has reached 0.5 mm the tyre needs to be reprofiled how is it possible?.
@@vikashthakur5863 Dear Sir, Thank you very much for your response. I HV given th circular which restricts the parameters in service. Similarly for diesel locos also it's similar but para para 20 of MP IB BD.02.16.01 REV 0 Also mentions about service limits. Efforts are always made to present data only with ref to rdso spec MIs, bulletins. Always appreciate and welcome your comments and would also seek your guidance where I m wrong. Thanks
Well I don't know about which theory is the remark, but if a locomotive has a in service tolerance of variation of wheel diameter on same axle how come wagons trailing behind can have no in service tolerance. My Gyan is personal experience of over 300 derailments i faced and I don't want want anyone to accept it. But I always try to put forth the data based on manual codal provisions appd by RDSO,RB . If it's in contradictory to rdso may kindly pin point ,i shall be happy to correct my self and criticism will make me further perfect.

Excellent description and a good presentation. Keep going
Sir, it's very nice description of differential wheel dia effects on locomotive stability. Very informative one sir🙏
👍
Sir the para just says that the difference is 1:6mm not mentioned that it is during in service.
Yes Sir, but it's when turning is needed.

@@vikashthakur5863 it's at time of turning and wheel fitting at roh poh. There is in service limit prescribed by RDSO
Sir before asking people to accept your theory which is in contradiction to Rdso letters i request to you to get your all Gyan approved by Rdso.
