Experts from the Indian Institute of Technology Bombay (IIT-B) have asked both Central Railway (CR) and Western Railway (WR) to remove the attachments of overhead equipment that have been placed under the bridges. The auditing committee comprising of IIT-B experts, officials from Brihanmumbai Municipal Corporation (BMC) and railway officers have concluded that the weight on the RoBs has increased due to these overhead cables and renders at least four RoBs unsafe.

The attachments are to give support to overhead wires, which provide power supply to the running trains. The weight of the wires on the bridges can go up to 1,000kg. The RoBs from which attachments will be removed are at Currey Road, Chinchpokli, Parel, Byculla and Grant Road.

“We have been asked to remove the attachments from the RoBs, which increase the weight on the bridges. The wire attachments are heavy and will be removed after undertaking blocks,” said a senior Central Railway official.

However, the railways has not decided by when it will remove the wire attachments.

The inspecting teams earlier asked that utility cables be removed from the ROBs at Ghatkopar and Kalanagar (Bandra East). Ghatkopar RoB is loaded with cables with a thickness of 400mm. CR closed down the pedestrian pathway on the bridge as a result of this finding. Similarly, Patri Pool RoB at Kalyan has been shut to vehicular traffic and a thorough inspection of Byculla RoB is also being done as the inspecting team found corrosion in the bridge’s structure.

After a section of Gokhale Bridge collapsed at Andheri station on July 3, IIT-B, the Railways and BMC embarked on an inspection of 445 bridges that cross railway tracks in Mumbai. Twelve teams have been formed to look at foot overbridges and road overbridges across the city. The audit is expected to be completed within three to four months.
