Nagpur: The Nagpur division of Central Railway on Monday took the first step towards restructuring the railway underbridge (RUB) at Gaddigodam on Kamptee Road by installing a temporary 25 tonne steel girder. On Monday, the Central Railway took a five-hour block from 5pm to replace the girder. “This 25 tonne relieving girder will help the movement of trains for now. It will be replaced in the second phase with cement slabs. The stage-II work is expected to be completed by month-end. The girder has been installed so that we get working space for final work,” said engineering department officials. According to officials, the earlier girder was damaged when a trailer hit the overhead railway bridge in December last. The traffic on this stretch is closed for over six months and is being diverted from Mangalwari flyover towards Sadar. However, officials said, “Even if railway work is completed, the road will remain closed for traffic for an indefinite period as MahaMetro has also started work on a double-decker multi-layer transport system between SFS Cathedral and Automotive Square. The Central Railway has already granted permission to start work in their area.” They added that 80 tonne pre-cast slab is to be laid at Gaddigodam for replacing the girders of the railway bridge. The work is running behind schedule owing to lack of workforce due to Covid-19 restrictions, they said. Once completed, the RUB will provide much-needed relief to passers-by who were a tormented lot whenever trains stopped over the bridge. Passers-by complained about toilet water dripping down the gaps in the RUB whenever the trains stopped. The RUB was constructed during the British era and the railway continued its use with minor repairs.
