Mumbai: A Metro journey on the Versova-Andheri-Ghatkopar (VAG) corridor may take longer than reckoned initially as the Research, Design and Standards Organisation (RDSO) has recommended a speed limit of 50 kmph. The RInfra-promoted Mumbai Metro One Pvt Ltd (MMOPL), though, insists that the final decision on speed limit has not yet been taken.
The RSDO-recommended cap, if enforced, is expected to lower the average speed to 25 kmph on the 11.46 km corridor.
Services on the VAG corridor are to start by the end of the financial year, subject to a nod from the safety authority.
The Metro Act says that in case of urban transport, new technology needs safety clearance from the railways. The RDSO is a technical adviser to the Railway Board and does technical examination of proposals received from various transport authorities.
“The RDSO has recommended a speed limit of 50 kmph for a period of one year,” Railway Board member (engineering) Subodh Jain said.
But the MMOPL insisted no final decision had been taken. “No speed restriction has been notified for operations. The issue of commercial speed is at present under consideration of the Railway Board. The RDSO has issued provisional speed of 90 kmph, based on which oscillation trials are in progress. The final speed of a Metro line is notified only after inspection of CMRS,” an MMOPL spokesperson said.
The Metro can run at a top speed of 80 kmph without compromising safety but the speed approvals had to be given by RDSO based on certain set standards, said a railway official.
The official said that work on the project was initially carried out according to the Tramways Act, for which the parameters were different from the Metro Act that subsequently came into existence. The official said that for projects started before the enactment of the Metro Act, there may be issues related to standards, but it does not mean the network is unsafe.
An RDSO team was in the city to undertake oscillation and emergency braking distance trials last week.
