To check safety of the proposed platform height of 920 mm, the expert committee appointed by the Bombay High Court, in its first meeting on Thursday, sent a resolution to the Research Design and Standards Organisation (RDSO), asking it to conduct field trials at nine platforms on Mumbai suburban system, where the height has been raised to 920 mm recently.
A testing train is scheduled to arrive from RDSO in Lucknow along with officials on February 22 to begin inspection at Andheri, Vile Parle, Elphinstone Road, Parel, Charni Road and Grant Road stations, said a senior railway officer.
The train, which will have a computerised instrumentation coach, will attach different kinds of suburban train and mail/express coaches to test the safety of 920 mm height at different speeds.
The trials will be conducted at night. RDSO will record the readings, analyse the data and submit a report to the expert committee. The committee has to give its comments on the report to the High Court on February 28. The railways will examine the recommendations and give its comments to the High Court on March 13.
“The testing train has a computerised coach which helps in picking up readings while the train is in motion. Different coaches will be attached to determine whether 920 mm is a safe platform height,” said a committee member, who attended the first meeting.
Since the platform height is not the same throughout the length of platforms, the expert committee has suggested that the research wing of the Indian Railways should take measurements at five locations along the length of platforms for more accurate data to understand the existing variations in the Schedule of Dimensions (SODs) for platforms.
