MTM Response to Recommendation RO-2014-016-SR-038
1. MTM agrees with this action.
2. MTM refers to and repeats the proactive safety actions already taken by MTM since the incident, as acknowledged in the Report.
3. In addition:
a) MTM has been pursuing a rulebook re-write and has obtained agreement from PTV and all large infrastructure managers who use the same/similar rulebook. The rulebook re-write will have specific focus on reviewing degraded mode operations. This will include consideration of the application of Rule 1 – Section 3.
b) MTM is continuing to apply the Train Protection Warning System (TPWS) in areas of the network utilised by V/Line and removal of dark territory on a riskbased approach progressively as projects are being delivered. A proposal to apply the TPWS to additional signals identified as a risk across the network (i.e. signals not already covered by projects) has been submitted to PTV for funding and approval. Regarding Train Protection Warning System (TPWS) whilst it is acknowledged that the application of TPWS will not enforce compliance with Rule 1 – Section 3, the facility does provide an ‘electronic’ train stop facility for the V/line TPWS fitted fleet.
c) In the interim, risk relating to Dark Territory continues to be managed in accordance with MTM's Enterprise Risk Management procedure. In addition to managing risks associated with Dark Territories, MTM is working with PTV to determine funding requirements and priority. The removal of dark territory, in conjunction with a re-write of the rulebook (as per above), will further support the management of degraded mode scenarios, including management of automatic signal failures which have a direct relationship to Rule 1 Section 3.
