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.
