HUTT VALLEY LINE ON-TIME RELIABILITY – ASSESSMENT MEMO
This memo seeks your approval to an increase in investment of $2,000,000, through a 100% Financial
Assistance Rate (FAR) in Greater Wellington Regional Councils (GWCR) Public Transport (PT) Programme for
Work Category 515 - Passenger Rail Services Track Access Agreement with KiwiRail to bring forward a
programme of maintenance and renewals to address on-time reliability issues with the Hutt Valley Line.
The Hutt Valley Line (HVL) is the name for the section of the Wairarapa Line railway between Wellington and
Upper Hutt. Frequent passenger services run on the line each day stopping at 18 stations.
It is recommended that you, acting in accordance with your delegations:
Note that there is an on time reliability issue for the Hutt Valley Line that can be alleviated by bringing
forward track maintenance and renewals via the GWRC Track Access Agreement with Kiwirail.
Note that the activity has been assessed for its impact on the NZ Transport Agency outcome Efficiency –
100% of Benefits. There are indirect additional impacts on the NZ Transport Agency outcome more
3. Note that the activity has been assessed against the PIKB assessment framework of Strategic Fit,
Effectiveness and Efficiency and assessed as HMH. The key efficiency benefit is reduction in travel time
for public transport users. At present an average loss of travel time of 10 minutes generates negative
travel time benefits of approximately $5 million per annum, based on an average travel time value of $5
per hour (combined peak and off peak values), delay of ten minutes and 6,381,948 passenger trips on
the Hutt Val ey Line.
4. Note that to provide journey assurance to commuters on the HVL it is recommended that the NZ
Transport Agency increases investment in GWRC Work Category 515 – Passenger Rail Services to bring
forward maintenance and renewal work under the Track Access Agreement with Kiwirail, reflecting that as
Kiwirail has other priorities for their investment under the Kiwirail turnaround plan, this work would not
happen to the same timeframe as desired by GWRC and the NZ Transport Agency.
5. Note that due to the need to bring forward maintenance and renewal activity under the GWCR Track
Access Agreement with KiwiRail this investment is at 100% Financial Assistance Rate for 2015/16.
6. Approve an increase in investment of $2,000,000 in GWRC Work category 515 – Passenger Rail Services
at 100% FAR.

The Hutt Valley Line (HVL) has experienced deterioration in asset level of service, resulting in loss of journey
time reliability and travel time predictability. This level of service loss is due to both general asset
deterioration now impacting on level of service and impact of weather events on the HVL. The level of service
impact is increasing use of speed restrictions on the HVL allowing services to continue to operate but with
longer journey times. This has flow on impacts on travel time predictability and of journey time reliability due
to longer trips, stacking at stations due and subsequent turnaround times at end of journeys.
Figures 1 and 2 below il ustrate this loss of journey time reliability and travel time predictability. The impact
performance is particularly acute for the Wairarapa Line components of the HVL. Total travel time loss varies
on a day-to-day basis, but the average estimate is 10 minutes of lost travel time.

Issues driving the on-time performance are catch-up renewals and maintenance on the HVL. This work is
programmed by KiwiRail, however funding for these works come from KiwiRail capital and payments under
the Track Access Agreement with GWRC. KiwiRail priorities for investment are aligned to those set out in the
KiwiRail turnaround plan, which focusses investment on freight movement, as a result the programme of
works for the HVL is a lower priority compared to the NZ Transport Agency priority for metro-rail services for
A one-off increase of $2,000,000 in investment by the NZ Transport Agency in the Track Access Agreement
between GWRC and KiwiRail will increase the priority for asset renewal and maintenance on the HVL to
address journey time reliability and travel time predictability. This opportunity supports the GPS 2015-18
short to medium term result for Public transport of increased network productivity on main routes within our
major metropolitan areas Options
In the absence of investment in HVL maintenance and renewals there wil be an ongoing loss of journey time
reliability and travel time predictability affecting the ability of the HVL to maintain its level of service and
address peak period congestion for the Wellington region.
With KiwiRail priorities for investment aligned to those set out in the KiwiRail turnaround plan, which focusses
investment on freight movement, the only option to increase priority of works on the HVL is to increase
investment in the Track Access Agreement to bring forward works in the HVL asset management programme.
The Track Access Agreement is a component of the GWRC PT Programme under Work Category 515 -
Passenger rail services.
It is recommended that there increased investment of $2,000,000 at 100% FAR for 2015/16 in the GWRC PT
programme Work category 515 – Passenger Rail Services, to bring forward maintenance and renewal works
for the HVL, to address journey time reliability and travel time predictability.
The GWRC PT Programme including Work Category 515 “Passenger Rail Services” has been included in the
2015/18 NLTP as HMH. Total work category funding is $145,773,449 for the provision of metro rail services
in the Wel ington. Within Work Category 515 is provision in 2015/16 of $18,000,000 to fund the Track
Access Agreement with Kiwirail. This agreement is subject to negotiation but in the interim will be adjusted
by CPI for 2016/17 and 2017/18.
The NZ Transport Agency cost for bringing forward renewals and maintenance under the Track Access
Agreement is $2,000,000 in 2015/16 and Funding Source N.

The assessment framework is set out in the planning and investment knowledge base (PIKB) http://www.pikb.co.nz/home/assessment-framework/
for the 2015-18 NLTP using Strategic Fit for Public
(which incorporates Work Category 515 Passenger rail Services with Track Access
Agreement costs being a qualifying activities). Effectiveness
was assessed as set out in PIKB with the
Wellington RPTP and Regional Rail Plan as supporting evidence for effectiveness. Efficiency was assessed on
Service Programme Benefits Cost Appraisal and a calculation of Travel time disbenefits under the Economic
Evaluation Manual (EEM).
Strategic Fit, Effectiveness and Efficiency
Investment in bringing forward renewals and maintenance under the GWRC Track Access Agreement with
Kiwirail has been assessed against the framework in the planning and investment knowledge base1
consistency to programme profile for GWRC PT Services. The assessment profile for this project has been
determined as being of High strategic fit, Medium effectiveness and High economic efficiency via the Service
Programme Benefits Cost Appraisal developed to assess the economic efficiency of PT programmes.
The investment achieves a ‘High’ strategic fit as it has the opportunity to address severe congestion in a
major urban area. This is evidenced in travel time and journey reliability measures on main corridors and
arterials across the Wellington network.
The investment is assessed as ‘Medium’ criteria for effectiveness, being the overall lowest rating of all the six
components of the criteria for effectiveness, being outcomes focussed, integrated, correctly scoped,
affordable, timely and confidence. This activity provides for consistency of level of service, consistent with
the current network and current and future activities, is appropriate in the scale of the opportunity and
mitigates adverse impacts on other results, is affordable and has traded off the best whole of life cost
approach, delivers benefits in a timely manner and delivers enduring benefits, and manages risk to outcomes.
This investment is assessed in ‘High’ economic efficiency via the Service Programme Benefits Cost Appraisal
and with consideration of the of travel time dis-benefits of $5m identified in the EEM.
Review of Economic Efficiency
The Service Programme Benefits Cost Appraisal Tool has been developed by the NZ Transport Agency to
assess economic efficiency of investments in Public Transport programmes.
As detailed in the Planning and Investment Knowledge Base (PIKB), the Transport Agency requires all
investments to be assessed across the Investment Assessment Framework (IAF). This includes both public
transport service and operations programmes and maintenance programmes. As part of this assessment, the
NZ Transport Agency determines both the efficiency of the existing service programme as of now, and in
future and any intended service improvements to ensure what the NZ Transport Agency is investing in is
value for money, and that the investment and service provision is being optimised. The Service Programme
Benefits Cost Appraisal Tool provides the methodology and an Excel dashboard tool to complete this
Under the Benefit Cost Appraisal tool the impact of increased investment in the GWRC programme is a
Benefits to Efficiency ratio for the GWRC rail programme of 4.8.
1 See www.pikb.co.nz
Further analysis based on the Economic Evaluation Manual for Travel Time benefits for Public Transport Users
identifies that non-investment will result in loss of travel time dis-benefits of approximately $5,000,000 per
annum (6.3 million passengers with 10 minutes travel delay, with average $5 per hour Travel Time benefit).
NZ Transport Agency Outcomes and Synergies
