Hi....
The Cyprus Govt railway was a fascinating system.....they had Kitson
4-8-4Ts to the Barsi design by Calthrop for example as well as many
other types....a very "British" colonial type system.
There was a book done many years ago...a very good one at
that..."Cyprus Govt Railways by Turner. Its now rare but if anyone
wants more info I have my own copy....or I will try to find one!

The center motor would need to engage with the rack
on the track, and the axle could get in the way. Of
course the axle could be removed (hasn't something
similar been done to the WDM2 to create another class
of BG diesel ?), but that would considerably increase
the load on the remaining axles.
It seems to me that the easiest way to equip a YDM4
or a YAM1 for rack operation is to attach a special
"slug" to it (a second unit only with traction motors
mu-ed to the main loco), the traction motors on
which would work on the rack. This would not require
major modification on the main loco. I suppose a slug
(also called "calf" in the US) could be designed
on to a standard YDM4 frame, without cab and engine,
equipped with rack motors where the center axles on
the bogies are usually located.
Does any list member have access to a MG shed ? I would
have liked to take a look under a YDM4 to get an idea
about the traction arrangement.

If this Poona Light Railway is built, the green space likely will not be
much of an issue. One of my more unfortunate impressions of India was
that
environmental or ecological considerations don't seem to have a high
priority in a country of almost a billion people: Hindustan Ambassadors
and
Tata trucks spewing out exhaust emissions that would be illegal in North
America, raw sewage belching into the Ganges, deforestation in the
foothills
of Rishikesh, air in Ahmedabad that was so full of particulate matter
that
you could almost chew it, big blobs of paan on every street and
sidewalk,
etc.
I didn't have problems with the smog in Delhi or Bombay, but Ahmedabad
had
some of the worst quality air I ever attempted to breathe (or chew).

It would seem to make sense to start with an Alco model in the first
place and
then modify it. The G12 has almost nothing in common with the WDM2. Even
a GE

I went to Mumbai on Monday by the Shatabdi

seem surprising that the route is witness
to frequent derailments.
What are the best track stretches on IR ?
I remember good rides on the Bhopal-NDLS

Yes, the center axle and motor is removed between WDM 2 and the super
ugly WDP 1.
How about attaching the rack pinion on the inside surface of the driving
wheel and
having the track rack just inboard of the rail. That way the only the
engineering
complexity of trying to mount the pinion in the center of the rails
would be
relieved. However to maintain either hood leading operation both the
wheels on an axle and both the rails would have to carry the rack and
pinion hardware. Or the rack YDM 4 loco would have to be driven strictly
in one direction (like strictly long hood leading in one direction).
Also the rack rail would have to be of a greater height than the main
rail, which is true in any case ? - fouling worries !
The slug is also a great idea. How much of power of the loco must be
used by the
rack engine ? If I remember correctly, the X class has smaller low
pressure
cylinders which run from the exhaust of the main cylinder. This points
to the rack
engine requiring a much smaller amount of power. It just provides a
surface to bite
on in the absence of adhesion. Thinking laterally from the X class
example, a slug
consisting of a concrete or steel weight on a single YDM 4 truck seems
good. The
truck may have the missing middle two motors from the main trucks. If we
could see
in the future, maybe this idea is not so bizarre after all.
Will the DHR benefit
from a rack section and is it a fact that the B class (or any steam
power) provides
better adhesion working than a NDM series power ?
I propose a joint trip of the Mumbai and Pune gang to have a look at the
Tambaram
MG shed for the YAM 1s. They are with us only for the next two maybe
three years.
IS Anand knows a lot of railway heavies in the SR at Chennai. So he
could help.
I suppose one can get access inside (and under the loco) provided a MG
shed exists
nearby. The nearest MG shed is Sabarmati/ Gandhidham/ Abu Road ? My
guess is that
the Guntakal shed is gone the BG way by now.
A few years ago Guntakal and Golden Rock used to provide all the YDM 4s
required in
the ENTIRE SR and SCR.

I don't think driving long hood leading should be a major drawback
on the rack sections: train speeds must be quite low. I am still
not sure how much space would be there on YDM4 axles for adding a
rack, but if any of us is near an MG section, one look under the
loco should tell us something. Fouling should not be an issue.
Maybe a rack only on one side would work, if there is place
on the axle for the pinion.

I am not familiar with the X-class, but I thought any
compound loco would have larger low-pressure cylinders ?
Power distribution between rack and adhesion should depend
on the gradient, I think, but I do not have the information
to do any rough reckoning on this. Axleload limits would need
to be considered if a special slug for a YDM4 is to be designed:
that would determine if a single truck would be adequate
or not. Asking SLM (or any appropriate supplier) to develop a rack
slug based on standard Swiss MG
rack equipment, controllable from a
standard YDM4, could well be far cheaper than a new class of steam
locomotive, or converting the route to electrification. Even
if we buy only power trucks from a supplier, the rest of the
slug can be developed in India.
I can think off the top of my head about a three-axled slug
with coupled wheels and one traction motor, something like
the WDS4 wheel arrangement. The traction motor would be
frame mounted, and pinions could be placed on the outermost
axles. Build ballast weights on this thing, and mu it to
a YDM4.....hmmmm.

According to Dr Walker, the DHR is already suffering from
slipping problems on severely graded sections. These could
theoretically benefit from rack addition, if the B-class can
also be modified. I am not sure how the tractive effort of
the NDM, and its axleload, compare against that of the
B-Class, which is what would influence adhesion. What
is the current status of motive power on the DHR anyway ?

Sounds good, and I hope I can make some time for this.
A stopover at NMR would also be a good idea, as I am
getting very curious about rack operation. The excellent
photos posted by one of our members (sorry I can't remember
your name offhand !) look very inviting also.

Subject: Railway Company Liveries
Date: 27 Oct 1999 09:09:08 -0500
All,
I have been asked by a friend to see if I can find out the liveries
used by various Railway Companies, including these Indian ones. He
has a collection of Company Crests which he wishes to mount on boards
in an appropiate colour. He needs to know the liveries of both
locomotives, and rolling stock and wethever the Company put its crest
on both loco and rolling stock, or just on one of them. The idea
being that he will then mount the crests on a appropiately coloured
board. The period of most of the crests in from 1919 - 1939. The
Railways concerned are:
W Ceylon
H.E.H. The Nizams State Railway
Pakistan Western Railway
E Bengal Rly India Stores Department
GIP
BBCI
Jodphur Railway
He also has crests from Africa, Australia, and South America so if
any one has any knowledge of these areas can we correspond off line?
Thanks

S.Srinivas,
There are two versions that I know of that are used in e-mail
communities. One is the type we use now, except when you reply it goes
to the server then the list members. Second is digest. What this does is
accumulate all sent messages over a 24 hour period then mails them to
list members as one message. This system is fine, if all you want to do
is read the messages, but for the people writing and responding it is
not very efficient. For example, If I ask about a certain train in India
as to where it travels, the members would not recieve it until the list
manager sends it. It usually falls around the same time of the day. Now
say you want to answer and do so by replying.I will not get the answer
until the next mailing. Now 2 days have passed. Second, what if 15 other
members answer. Now all list members get to see the answer to my
question 15 times. Now I know most people read down through their mail
before replying just in case someone has answered another, but with
digest, this is impossible to do. I suggest that we get a community that
offers both options <A HREF="http://onelist.com/">http://onelist.com/</A> is one such community that I
have had no problems with. If you go to it you can search out subjects,
such as railroads, and they will all pop up and can be browsed. Archives
are kept daily and you can go back to them. Photo archives can also be
kept. We can even do surveys! All we need to do is set it up and then
everyone subscribe to the list. It is free. An address for mailing could
be something like IndianRailways@onelist.email. Somebody mentioned "list
bot" I think this list only sends in digest form.
Well, just my 2 cents,(paises), worth.

Date: 27 Oct 1999 10:11:01 -0500
Hello,
There was a thread on this some while ago.
The long and short of it was, it was unanimously agreed at that time
that nobody, including the National Rail Museum authorities themselves,
know exactly what sort of livery was actually used on the trains of the
various princely railways.
At any rate, all old records are in black and white, and no one really
bothered to find out or record accurately the liveries of yore. The
liveries applied to the exhibits of the nrm are also suspect. When the
museum was inaugurated in 1977, someone claimed that the engines have
been painted in exactly the same colors they originally bore. That was
in R.R.Bhandari's time. Subsequent livery changes have occured over the
years.
To quote an example, the dimunitive diesel engine from the Betty
Tramways, Rajkot was originally in milky white color with sky blue
embellishments. Now its sky blue with a maroon nose!
GIP electrics were always painted a sombre black with red
embellishments. The EA/1 and EF/1 there are now black with light
blue/white embellishments. An infuriated irfca member once referred to
them as 'park livery'.
Its somewhat like the Jones goods 0-6-0 engine preserved in England,
wearing a yellow ochre livery which a guide book said she never bore
while in service.
I think the situation with crests was just like it is now. Officially
all engines carry 'INDIAN RAILWAYS' on their sides, (or sometimes
SOUTHERN or CENTRAL etc. Cars have ER or CR or SC on them, with the
round IR crest painted on the side centre.
All the pics of historic trains I've seen were similar. The engine
carries GIPR, or BB & CI or MSM etc. on its side, with the crests on
some (but not all) cars on the bottom.
The nrm shows some engines with the crest fitted onto their smokebox
doors (MSM crest on the FMA's smokebox door, BNR crest on the RD's
smokebox door) etc. But did they really exist that way?
Any ideas/deviations, gang?
Cheers.

Subject: Re: Rack-equipped YDM4
Date: 27 Oct 1999 21:44:52 -0500
Just to send back my view: Dr Walker is very right: From all
points, steam in NMR is best what ever. What I only wanted
to forsee is what would happen after the age of steam. It was an
utopia. Of course NMR could not turn into a vehicle reduced (like
Materan),ecologically proteced (because of mountains
=landslides), real south-indian mountain-jungles could be observed
without any traffic-noise echoing...
First to make an ending point about of the YDM 4 to put up in the
mountain - with a calf or what ever... what I ever found out in SITU
was:
The upper section was converted easily to YDM 4 BUT the rack
section
restricts the YDM 4 from NOT because the gradients are to steep,
BUT the
radius of the curves of the rack-section (remember Glendale
Estate) are
simply TO SHARP to let a YDM 4 run there!!! Forget it! They only
got the
"Bluy Diamond" there because, SR lifted it by steam-haulage up to
Coonoor.
Any serious consideration of changing the traction power on the
NMR from Steam could only lead to the decision: Grading up the
line (improving laying and axle-loading) electrify it (YAM! on the
upper section and something else - SLM has some aproved
technology here as well - on the rack-section) and put a lot of traffic
from road (as tourists of course and as well as goods!!!) to the rail
even
if necessary by REGULATIONS. This means, as others members proposed, a
clear evaluation of all aspects. The is a local interest to support the
railway as well as it is a national monument. Not only the construction
of
it self but as well as the entire, operation on the entire, so called
"third world", runing successfull in Indian Hands since almost Fifty
years!!! Dr Walker is right, I must addmit:
* NMR is absolutely unique in the so called "third world", witch also
leads to the next point of Dr Walker:
* The PERUMKA have extensive problems with their diesel-racks.
These are sophisticated ones frome the prime manufacturer in the
world BUT they are really getting already their second batch since
Dieselisation 15 years ago!!! Apart from that, their is no succesfull
runing, diesel-operated rack-railway in the world. Their are some of
such
diesel-powerd vehicles in Switzerland but these are marginal and one
must
consider the exellent state of Swiss railway maintanance. As far as I
Know, this line is mostly used for ore-traffic.
One exception: the 750mm gauge rack-railway (Abt like NMR) in
the north of the Ploponnes-peninsula of Greece (Diakopto -Klavrita)
is dieselized since the mid-60ties BUT with electric-powerd
railcars, supported by a generator-van, equiped with a Diesel-
engine and a DC-generator, coupled between the railcar and the
sub-car, whilst the latter is always shunted by the railcar mountain-
wards, whilst the generator-car is always coupled in between. A nice
operation, still running in 1999 (Eye-witnessed this year)! Actually,
everything was made to order a later elctrifictaion of the line with
easy
conversation of the DC (750 V) powered rail-cars to OHE (which in fact
never took place until nowadays) but in wintertime, when the road is
blocked by snow, its the only link for the Kalavritan-villagers to
access
the outa world.
As I have followed the news especially from the produceers side,
there is no way of any import of "new-way"-steamers (proposed
designs from SLM) because of "to expensive" (without evaluation).
Enough of speculation. Anand IS observations from Golden Rock
prove, that there will be some time left to get more awareness.
That is what I really meant: If Anands observations proves right,
WE get another 3 years time to build up more awareness (in the
public) about what´s up in the hills.
India is changing a lot since some years and will might do more in
the next millenium.
What really build my up was the news about the HGS steaming
out of Howrah.... How ever belived that would happen??
So much for now, excuse to everybody witch mind i´d upset.
Heinrich
BTW, we had a lot of Rack-railways here in Germany and they all
went to adhesion. Remember only the Ruebelandbahn: It is with
1:16 not that steep like the NMR but the racks were already
substituted before electrification (from DB-net isolated 25kV/50Hz-
System) by the "Animal"-class steam-locos and the main traffic
here are heavy bloc-trains loaded with lime. The most powerful
german locos are deployed here.
Whatsoever, it is a question of attitude to the region and the

Jayant,
Can you be specific, which section you had a rough ride and I can get a
comment from the PWI dept. I remember the section near Neral as being
really bad.
The news I have heard is that in the suburban Mumbai section, the slow
tracks have had their bed height has been increased to cope with the
water logging. So the EMU entry height above the platform has become
excessive. Many ladies are seen sitting the door of the EMU to get down
on the platform as a jump is difficult. This may be an exaggeration by
the person who told me this news but Mumbai gang could verify the truth
easily.
The ride quality Howrah - Nagpur is full of violent sways, lurches and
bottoming of suspension elements. Once the train enters the NGP - CSTM
section, it is comparatively smooth.
