Dear Shri Roy,
I am retired General Manager /Southern Railway and have worked for five years in the Research,Designs and Standards Organisation.I was associated with high speed trials in 1974.
The IR have laid criteria such as vertical accelerations, lateral accelerations, vertical and lateral track forces.These crteria have become stricter over the years.The vehicle is tested at increasing speeds till the limit of these criteria is reached.
The maximum permissible speed is limited to 90% of the test speed.For example,if a train is to operate regularly at a maximum speed of 100km/h it is tested at 110.km/h
The Indian Railways have a very clear cut procedure for introducing new types of coaches, wagons and locomotives.If they are indigenously developed, the RDSO issues a provisional speed certificate for a limited speed not exceeding 75 km/h.
Even if the vehicles are certified by a foreign supplier, the provisional speed certificate has to be issued by RDSO.
Thereafter, Oscillation Trials are conducted.The trial speed certificate is issued by RDSO, usually in consultation with the Commioner of Railway Safety.
After successful completion of trials, the final speed certificate is issued by RDSO and ratified by the Railway Board.
Each Zonal Railway has to issue its own speed certicate which is signed by the Chief Civil Engineer, Chief Mechanical Engineer and Chief Electrical Engineer.
The article in Asian Age is totally misleading.
TALGO trains have been operating safely for over sixty years in Spain.I understand that the TALGO trains have passed the Oscillation trials successfully.
Unfortunately, Indian Railways still does not have a dedicated test track, forcing it to carry out trials on existing commercially utilised tracks, which is definitely a cause for concern.
I request you to use your good offices for getting a dedicated test track for IR.
May I have a copy of your RTI application and the reply?

Subject: [IAC#RG] How corrupt / unsafe is Indian Railways / Railway Board ?
The railway safety body has questioned the Railway Board on how trials were conducted without its permission.
