A design modification is being sought for some electric double-decker buses due to height issues. The buses' roofs have been found to be too close to the underside of a flyover, causing clearance problems. To address this, a reduction in height of 17 cm has been requested.

The issue has affected a particular route, where the buses have been found to nearly brush against the flyover. Further details about the design modification and its implementation are available.

The buses in question are around 457 cm high and have been in operation for over three years, offering air-conditioned electric service.
