Rolling Highway 

Ways to protect the environmentally sensitive area between Lithgow and Katoomba
AND
keep people and freight moving...... the Rolling Highway 

(Back to Home page for a quick overview)

A little bit of technical information

We can introduce trucks (and cars) on trains here too.

The Europeans call this a “rolling highway” or RoLa– cars and trucks drive on and off flat bed rail wagons at the beginning and end of a journey.  This is a very viable proposal, instead of a four/five lane divided road carriageway through Blackheath and Medlow Bath. The rolling highway would have terminals at  Marangaroo and St Marys as both are close to main roads. A cheaper alternative to St Marys would be to make minor alterations to the existing intermodal at nearby Rooty Hill, which is currently used only by Holcim.

See how it works here:  Rolling highways between Austria - Italy and Austria - Slovenia

What will it cost?

Hundreds if millions of dollars (compared to thousands of millions for the  proposed road expansion). See below for rough estimates.

What will be involved?

Very little initially.

• Extend the wires (catenary) from Bowenfels to Marangaroo – 3.5km

• Acquire flat bed rail wagons for drive on / off

• Purchase new high powered locomotives[1]

• Construct intermodal terminals at Marangaroo and St Marys or Rooty Hill. IMTs for rolling highways require little more than a hardstand area, several spur lines and weighbridge etc) and the Rooty Hill siding is only used by Holcim for a maximum of 4 trains per day.

• Schedule more passenger rail services and promote them widely 

• Quadruple the rail line between Penrith and St Marys (from 2 to 4 lines) - this is already being planned by TfNSW as part of the expansion of St Marys into a transport "hub".

• Add power stations to cater for new high powered electric locomotives

• Possible need for power conversion from DC to AC for part of the line (Penrith to Lithgow)

Technical Note on Infrastructure.

The trucks on trains will have the same “loading gauge” (height and width) as current rail carriages[2]. Note that this will initially limit the height of trucks to about 3.5 m depending on the diameter of the carriage wheels and the floor height (in Austria and  Germany they vary from 350 to 410mm).

Minor modifications to tunnels and other structures, however, as has been done to accommodate the new Regional Rail Fleet [3], such as notching in the Ten Tunnels , will allow truck heights of 4m, as is the case of most of Europe. The new passenger fleet (D sets, due in 2021) will replace the V sets which has required some structures from Springwood to Lithgow to be widened. Major stations like Katoomba, Mount Victoria and Lithgow have also had platform length extensions. A  bridge between Penrith and Emu Plains was replaced.

There may be weight and length restrictions too but these can be overcome by using shorter trainsets and banking locomotives, as well as passing loops.

Gradients and Curves

The Blue Mountains line is at the  full extent of gradients for freight with a ruling gradient of 1.33 (3.1%) between Valley Heights and Katoomba. An equivalent route is the Brenner Pass between Austria and Italy where the ruling gradient is also 1.33[4]. A rolling highway has been in operation on that route for many years.

Power

The current Sydney system is 1500v DC, and the Blue Mountains line may require a change to 25v AC depending on weight of trains. AC would provide more power than DC to cater for the grades between Valley Heights and Katoomba. This means that electrical sub stations and catenary may need replacing / upgrading. Only the Blue Mountains line from Penrith westwards would need conversion (much of the infrastructure on that part of the line is old and would benefit from replacement).

However, 

 "significant technological changes in diesel electric locomotives. In particular, these changes to greater efficiency, “gripping” power and reliability to the locomotives create vastly improve the capability of moving freight on the long 1-in-30 grades on the Maldon-Dombarton line. The original plan in the 1980s required the electrification of the line but, by 1996, electricity charges had increased significantly, making electric-powered locomotives less economic compared to the diesel ones. 

Operators such as Pacific National no longer use electric locomotives and, if the Dombarton-Maldon line was electrified, there would be considerable difficulties finding commercial electric locomotives to service the line. Diesel-powered locomotives offer relatively greater flexibility in that the only restrictions on its deployment will be axle loadings."

NOTE:  the maximum gradient on the Blue Mountains is 1-in-33, slightly less steep than Maldon-Dombarton

However it was considered necessary to use electric locomotives that can be done.

In Europe, some locomotives are equipped to operate under four voltages - 25 kV AC, 15 kV AC, 3,000 V DC and 1,500 V DC. Modern electronics makes this possible with relative ease and cross voltage travel is now possible without changing locomotives.

The new D sets are 1500v DC and they too would need some retrofitting / conversion to dual voltage (1500vDC and 25kv AC) and there are now AC traction systems suitable for conversion of any type of DC rolling stock.  The same company that does this is also involved in the consortium responsible for the new regional fleet.

[2] Eg. the V-set trains: Height is 4.38m, width  is 2.93m.
The maximum height of a train in NSW is 4420mm,
The maximum width is  2930mm.  Source: TfNSW Technical Note – TN 005: 2019 p.7
The maximum height of a truck on a flat bed rail car would be about 3900mm
Standard ISO dry containers are (2.3m) wide, (2.3m) in height, thus allowing a container could be accommodated on a truck with trailer height up to 1.6m high

Costs 

Please note that it is very difficult to give any firm idea of the total cost of rail projects in Australia as the data is not readily available in the public domain. The figures below are rough estimates. 

Locomotives: eg. Siemens Smartron @ $4-5 million x 20 $100m[1]

Low floor wagons @ $1m  x 100  (5 consists)                $100m

Catenary(and substations): 110kms x2 @  $2m / km     $ 500m[5]

Conversion of 55 new D sets (50%) to dual voltage        $  50m

Add dual voltage to Regional Fleet (19 power cars)         $  25m

Quad St Marys to Penrith 8km including
relocation of Werrington and Kingswood stations                                                              
16km of track @ $12m/km and 2 stations @ $400m each     $ 1000m[2] [3]

Intermodal at Marangaroo  (3 sidings 500m long, roadworks)           $  50m[4]

Intermodal at St Marys or modifications to Rooty Hill Holcim IMT)    $ 100m

Road works at St Marys / Rooty Hill Holcim IMT [6]          $ 100m

Rough total $ 2000m (using electric traction)
If not using electric traction take off about $500 = $1500 million Or without quadding of Penrith to St Marys about $800m +/-

 Ongoing costs

•      Incentives for freight forwarders and weekend visitors to Blue Mountains.

[1] Cost of Smartron locomotive in 2018 was €2·5m = $4.1m AU

[2] may not need to be done initially, depending on train path availability between Penrith and St Marys; Port Botany Rail Line Duplication cost $400 for 3.5km which involves considerable bridge / underpass work and traffic diversion working in a congested brownfield site.

[3] “NSW construction cost per track kilometre was $48 million. The rest of Australia average cost per track kilometre, (based on 4 projects), was $27 million. However, it should be noted that the sample set contained both greenfield and brownfield and passenger and freight rail projects and projects also differed markedly in size. “p. 7 Infrastructure - Project Cost Benchmarking Study NSW Department of Transport  15 June 2011  Greenfield???

[4]  Passing loops at Rydal and Georges Plains, each 1.8kms long - $21.5m in 2019, c. $6m/km including turnouts
[5] Cost of conversion of Lisbon to Cascais (Portugal) from DC to AC in 2020: 25km double track cost €77m ($125mAU for 50 track kms or $2.5m / km)
[5] $115m Cabramatta Rail Loop

What about the medium to long term?

Reform road pricing system: distance, time and location based rather than on a one off rego / fuel excise charge. 

First, use annual odometer readings but make it optional. People can choose the old system, and for flexibility have GPS system which only stores kms and not temporal-spatial data.

Later introduce time and location based charges in addition to first step
So if you then want to drive your car to Blackheath for the weekend you will pay extra, OR if you take the train you will pay nothing.

Letter to SMH 7th May 2021

On average, more than $1000 per vehicle is spent each year on roads and related infrastructure for the benefit and safety of all motorists. This revenue must be raised by some form of taxation. The best solution is a charge per kilometre calculated from GPS tracking of the vehicle. This allows a higher charge in certain areas of a city such as the CBD to discourage entry. A danger is that if the running cost of electric vehicles becomes almost zero, fewer commuters will use public transport and roads will become even more gridlocked. Geoff Harding, Chatswood
