••• a"·Drivers are now being counseled for use of dynamic braking in regulating speed duringobservation of temporary/permanent speed restrictions to avoid any brake binding.Imposition of speed restriction on the approach of gradient is being done judiciouslykeeping in mind the approach speed requirements and steps are taken forremoval/relaxing the same at the earliest. Besides this, trains are also examined for theircorrect leakage rates so as to avoid brake binding during running. It was intimated that allIr ;Jirl~; uru t)(:irlU clleckncJ at BHTK for brake binding. .5.0 Study of Khurda Road Division of S.E.Rly:. IIKUR division of S.E.
