The Central Railway has begun cleaning and repairing several sections of the CST heritage building in the new phase of restoration that will be completed by March next year.
Officials are not using any chemicals, which could ruin the look of the UNESCO world heritage site, and are instead relying on brushes and a high pressure water jet to clean the darkened exterior.
Four spiral staircases are being repaired along with the handrail of the central dome balcony and the stone parapet on the first and second floors. The stained glass windows, one of the most striking features of CST, are also being fixed.
Defaced gargoyles and damaged original flooring are being restored, and a new 1,000-sq ft garden is being constructed on the eastern side of the building.
The Rs 1.5-crore project is being executed by a private firm. “The work should be completed in three to four months,” said CR general manager Sunil Kumar Sood.
