TIME TO LOOK BEYOND THE HORIZON
By
John Parry

Invent a better mousetrap and it is said the world will beat a path to
your door.
Invent a new type of rail vehicle and there are people who will do their best to beat you into the ground.
|

After
4 years, a project to install Britain's simplest passenger vehicle on
Britain's simplest length of public railway line is still apparently several
months away from resolving all outstanding operational issues. There have
been over 100 meetings and 2,500 items of correspondence, 5 different
Railtrack Project Managers, 6 consultants needing to be employed, 5 different
safety bodies involved, £150,000 of expenditure, not counting the
vehicle and 2,000 miles run in trials, testing and driver familiarisation.
There
are railways and there are railways. Official approval to carry the Public
in PPM trams on four private railways, at Welshpool, Bristol, Caernarfon
and Kidderminster, took on average a painless 6 weeks and about £5,000
to arrange. Within the organisations of Britain's rail network all matters
are professionally conducted and few items of detail unreasonably raised,
but taken as a whole, the amount of work and time involved must seem extravagant.
Removing
Car 12 for a full engineering check may create a valuable breathing space.
Nevertheless,
Parry and its associates are not ones to give up too easily and in November
the inevitable letter was sent to the Strategic Rail Authority pointing
out just how difficult, and arguably unnecessary so, the industry's procedures
were. The response came back promptly describing just how helpful
the industry had in fact been. My reply was as positive as possible: Recalling
the words of the Damon Runyon character who found himself broke and in
a sewer, anything that happens from now on can only cheer me up!
Meanwhile
the threat of war and world recession has affected, but not strangled,
Parry Associates' machinery export market. Orders and enquiries continue
to arrive from all over the developing world. As expected, while construction
there remains a priority, transport is now beginning to climb up the agenda.
Out of the blue we hear from one of our most successful tile equipment
customers in West Africa that a national Transport Ministry has realised
that one answer to chaotic road traffic congestion is to use the old 'colonial'
railway to create suburban passenger transport corridors, rather than
cut swathes through the city, building 4 lane highways. To transport the
same number of people by rail would use a quarter of the space. It was
this realisation in the late 1980s which laid the foundations of the People
Mover venture.
PPM
is now actively responding to each such interest from overseas markets.
But the export campaign must be founded on domestic 'showcase' projects,
so the implementation at Stourbridge is still strategically important.
Nevertheless, running there just one day a week on the quiet day of Sunday,
will restrict the rate at which operational experience is gained. This
is why in future months more will be heard about our previously-announced
strategy of seeking operating revenue by co-operating with the preserved
railway companies in putting PPM vehicles into service. Quite a few of
these even prefer carrying passengers on their trains than briefcases
to meetings.
The
'radar' has therefore to be more finely tuned to situations where those
on the frontline are empowered to take key decisions. An endangered species
in New Millennium Britain.

PPM CAR 12 RETURNS
|
|
| |
Light
Railcar brought back from Stourbridge for full engineering inspection
|
| |
As
the long winter break approaches, with no consent so far obtained from
the Railway authorities for PMOL, the prospective operator of the Sunday
railway services, to construct a light maintenance depot in its leased
area at Stourbridge, serious concerns over the safety of the vehicle have
provoked the decision to bring it back to Parry workshops at Cradley Heath.
Centro
and the Network Rail Zone remain confident that even after the long delay
since the vehicle was moved to the Stourbridge line on June 2nd, during
which officials have toiled with the procedural processes involved in
establishing the experimental service, all issues can be resolved by February
2003. The delay in itself has brought about an increasingly difficult
situation for PPM.
The
main risk is of being asked to put the vehicle into service after extensive
running trials since March 2002 under Engineer's Possession but without
any all-over engineering check. Such a check is only possible if the underframe
of the vehicle can be inspected from below. Stood on an ordinary ballasted
track without pit or hard floor for safe jacking, this is not possible.
The railcar was brought back to Cradley Heath on November 21st and will
be able to return to Stourbridge when all regulatory and technical preparations
are complete for it to enter service.

ACCRA IN A JAM LOOKS AT TRAM
|
|
| |
Authorities consider rail based solution to intolerable
traffic congestion
|
| |
We
are indebted to Tim Gamor, proprietor of Piege Construction, a Ghanaian
company which began building houses using Parry roofing tile technology
15 years ago. Tim has been researching a situation which is of considerable
interest to Parry People Movers. Despite efforts at highway construction,
including a dual carriageway ring road, the growth of car use in Accra
has been overwhelming.
According
to a ministry paper the extra cars have brought about :
|
- |
heavy
road traffic congestion in the Accra-Tema metropolis |
| - |
lateness
to work resulting in reduction of working time |
| - |
increase
in fuel consumption |
| - |
high
road maintenance costs |
| - |
increase
in environmental pollution |
| - |
increase
in road accidents, in some cases resulting in loss of lives and properties. |
During
a visit to Ghana by John Parry in the 1990s Tim and he drove down to James
Town where an unused spur of Ghana's national rail system extends to the
seafront. Even with the much less congested traffic at the time the opportunity
was noted to introduce the use of trams along this line.
This
has now been noted by the Ghanaian government transport authorities which
have produced a paper proposing conversion of three existing lines to
suburban commuter rail services. These run from Accra centre to James
Town and other lines radiating out to Tema, Achimota and Nsawam. The Ministry
have been made aware of the possibility for the PPM mode to be used for
this purpose. Discussions may take place in Accra in the New Year.

PPM CAPITAL BASE
|
|
| |
EGM
sanctions expansion of PPM capital base
|
| |
In
early November, PPM's board called an EGM to discuss the financing needs
of the company in view of the pressing problems caused by the disastrous
delays in the 'showcase' Stourbridge Project. It was recognised that a
delay of over a year in licensing the Sunday service had begun to stretch
the finances of the company beyond the extent that existing shareholders
could be reasonably asked to cover.
The
current Business Plan has described an 'identifiable' market base of over
800 vehicles which could go into service in the UK alone, but this market
will not be opened up if the technology cannot be satisfactorily showcased.
It is not unusual in the history of technical innovation for the point
of market threshold to be the period of greatest stress. (The air is thinnest
but the weather worst at the top of the mountain.) PPM's travails are
well documented. The EGM on November 26th was sparsely attended but the
general spirit of shareholders was registered in letters of support and
proxy votes. As recommended by the board, it was agreed that up to 300,000
£1 ordinary shares could be made available to new shareholders,
in effect extending the discretion provided at the previous AGM, in September
2002, which was limited to 5% of the issued stock.
Having
the discretion to dispose of shares is not the same as identifying suitable
buyers and bringing in the cash, and PPM's board is now engaged in the
task of tracking down essential funds needed to see through the Stourbridge
project and maintain its efforts to put PPM railcars into passenger service.
At an earlier meeting in September members of the 'Car 11 Syndicate' met
at Cradley Heath to review the market prospects for this vehicle and to
decide its future. The group very much approved the result of the recent
make-over which transformed the vehicle from narrow format railcar to
heritage style District Tram.

NEWCASTLE OPPORTUNITY
|
|

Newcastle
stakeholders discuss Arena shuttle opportunity
|
| |
Newcastle
on Tyne Central Station has a problem. Despite the imposition of a healthy
parking fee, such is the demand for spaces for the cars of people travelling
on Virgin and GNER services to Scotland and the South, that by 8.00 am
there are none available within convenient walking distance of the station.
Less
than a mile to the West of the station there is ample daytime parking
space behind the Telewest Arena but no easily implemented way of getting
from one to the other - except possibly by rail. Similar in character
to the Stourbridge shuttle service, the prospect has been noted by the
Passenger Transport Authority, NEXUS, of establishing a rail based people
mover service, in Newcastle's case employing partially used sidings. In
very early stages of investigation the Director General of NEXUS, Michael
J Parker, visited Stourbridge in August 2002.
Subsequently representatives of PPM and PMOL have visited Newcastle to
look at the situation on the ground. A meeting of local stakeholders was
called in early December to discuss whether the project should be fully
evaluated and a plan of action initiated. Further news is awaited.

ULTRA
LIGHT RAIL EARLY HISTORY |
|
| |
|
| |
During
ongoing literature search on passenger rail vehicles the occasional examples
emerge which establish just how lightweight and low tech the rail mode
can be in suitable circumstances.
These
photographs appeared in 'Atlas of the World's Railways' without captions.
The left scene is thought to be in South America, and the right in Senegal.
An interesting point: pulling a cart with road wheels, the small donkey
would struggle to transport more than 2 people. With steel wheels on rails
he can move 8 people and a driver. The Energy Saving Trust, please note
- to use energy more efficiently first switch your mode from road to rail.

PPM LIGHT RAILCAR - OPERATION AS A BUSINESS
|
|
| |
Experience
from PPM Car 12 'shadow' service operation on the Severn Valley Railway
and at Stourbridge provides useful guide to the operating characteristics
of the 50 passenger vehicle.
|
| |
Excluding
depreciation and other overheads, the operating costs of the PPM 50 light
railcar calculated on an hourly basis are now estimated as:-
| Crew
(2 persons) |
£14 |
| Fuel
(lpg equivalent of 4l. petroleum) |
£4 |
| Technical
support £10,000/year / 2000 hrs operation |
£5 |
| Spares
and consumables £10,000/yr |
£5 |
| Insurance
etc £12,000/yr |
£6 |
TOTAL |
£34 |
The revenue which the vehicle will be able to earn is calculated out of
the two factors of fare and loadings.
The
situation which is most immediately applicable is the prospect of operating
in service on a heritage railway. PPM has made an analysis of the revenue
per passenger carried on an hourly basis on the 37 heritage lines on which
significant operating distances are run. The average round trip journey
length is 1 hour 15 minutes and average adult return fare £6.76.
Allowing a factor for concessionary fares this indicates a potential income
of about £4.00 per passenger-hour on the railcar.
The
cash break-even point is 9 passengers are on board. Discussions are taking
place with several heritage companies regarding introduction of railcar
passenger services on their railways at times when patronage levels are
too small to run trains. car vehicle such as a PPM 50.
The
prospective arrangements between PPM and these railways for PPM 50 or
PPM 50/2 railcars to be put into service are based on alternatives.
Under
Option 1, the operating railway will meet the cost of providing crew and
fuel, PPM all other costs and fares revenue split equally.
Option
2, the railway company meets all operating costs out of the fare box and
the residual income is split.
As
a guideline to a successful business case we have assumed when operating
with light rail type frequency. The theoretical ideal operation is based
on the lowest average passenger loadings of trams on 6 UK light rail systems,
eg 24 passengers. This will, however, be seen as a high load factor for
a single car vehicle such as the PPM 50.
Therefore
in a 'mature' operation with regular routine services, the model of vehicle
used is likely to be a PPM50/2, a twin car unit with a power car and driving
trailer illustrated above. Purpose built for standard structure-gauge
railways, this unit will seat 62 passengers.

FLYWHEELS AND HORSES
|
|
| |
Experience
running Parry railvehicles provides insights into flywheel design |
| |
If someone goes to a dealer to buy a horse, it is sensible to clarify
whether what is needed is a horse to trek over the hills, to enter a race
or pull a heavy cart. The first similarity between a flywheel and a horse
is that you 'feed' it and it then gives you back some useful energy.
Like
horses, energy storing flywheels can come in different sizes and speeds.
The 'carthorse' application requires a heavy, wide-diameter unit suited
to pick up energy at a stop from an external source such as a short section
of electrified rail then moving at slow urban traffic speeds to the next
stop and recharging point.
The
'racehorse' flywheel is a relatively lightweight unit which provides additional
energy for acceleration, more than doubling the power available from a
prime mover such as a small internal combustion engine. This version will
be fitted to 'long range' PPM vehicles operating on railways which are
level or comprise lengthy rising gradients.
A
third category application is a railway or tramway on an undulating topography.
In such circumstances a medium size and weight of flywheel will take in
braking energy on downhill stretches and release that energy to supplement
that from the engine to climb the subsequent up gradient.
