iv. Modification of the D1 emergency valve for increasing its height

In light of recent instructions to crew, the ALP was advised to be in alert and standing
position in the event of an approaching signal aspect and also, he must be ready to
apply the emergency brakes. The existing height of the D1 emergency valve (120 mm to
floor) was not sufficient for the reach of ALP in standing position. As such shed has
performed a modification to the emergency valve to increase its height (400 mm to floor)
which the ALP can now easily reach without compromising the signal aspect. This
modification has been completed on 07 locos so far and in is progress.
