The CEE’s office will be responsible for ensuring that (a) the instructions received from
RDSO are forwarded to the loco sheds and (b) the superseded instructions are cancelled,
withdrawn and destroyed, preserving one copy only for future reference. Instructions received from
RDSO require constant review and a system of generating feed back information on the
implementation of these instructions will be followed. Any modifications required in RDSO's
instructions should be carried out only after approval from RDSO is received.
These technical instructions require constant review in the light of experience. If any
modifications become necessary, Sr.DEE (RS) may introduce changes provisionally with the
approval of CEE. Such changes should, however, be advised to RDSO for scrutiny and final
incorporation in the documents.
