Re: layout and rail questions
- From Wolfgang (Bolt) <<wbolt1809@...>>
Some suggestions to Jacob's questions:
Although I do not have a real layout - shame on me, I know ! - planning it
more and more sophisticated.....keeps me away from tranferring it into
No doubt at all: MT locos have originally by far better traction qualities !
But what, if you prefer "Europeans" ??! Without any modification, it's better
to have no grades of just those up to 2-3% - this is commonly agreed and
experienced for a long time.
Putting on weight - lead for example - is surely a remedy, but not always and
on all types of locos applicable, space........- perhaps you followed the
discussion just 2 weeks ago on the mailing list of the "Z-Club-92" .....
When I suggested to try traction tires on Diesels and E-locos, like used in
H0, I was confronted with the arguments: Improving traction ability versus
lack of contact for taking up electricity and possibly higher danger of
derailing on turn-outs.
I did it all the same ! What I had seen already before on demonstrations,
turned into reality: My "Heizer-Loco" (a series "460" from the Siwss
Railways, one out of the double loco-pack "88445") had no problem at all to
"climb" a grade of more than 30%......the following one must see or
experience oneself: A Diesel - BR 218, catalogue nb "8880".....made its way
"uphill"....on a grade of 45� (in words: degrees !) - which is, give me some
time to calculate......a grade of 58%.........(difference in height was 25
cm, ....."length" of track run......:43cm......) - As everyone can easily
understand, testing how many cars my loco would pull easily on a grade of
let's say 4%, is up to now really impossible........what I try out now on a
grade of 6,9% - you should see me right now, looking for kinds of weights to
put on a flat - "8610" car (6 gramms) !!! - I decided for a "Zippo"......60
gramms......and my loco nearly wanted to take off like a Jumbo Jet.......A
normal German reefer weighs 5-7 gramms...... - next try: grade 3,5%, same
loco, 2 cars to put weight in/on.....I stopped my trials, after the loco
managed to move "uphill" with a total of a little bit more than 400 gramms
I am pretty sure that just 1 or 2, but "heavy" car(s) is not the same as 179
(?) simple cars and that curves, turnouts and different radii have certainly
influence on the traction "capacity" !!!
Above all - it was great fun to do all this - perhaps you can imagine.... -
Oh yes, the price for 2 axles modified, including shipment in Germany, is not
more than DM 30...
Due to the linkage (please let me have the right expression, US-folks !),
traction tires are not yet available for steamers.
Perhaps, somebody has an idea, how to do this more easily without having to
dismount the "linkage" from the driving wheels of steamers - maybe some kind
of liquid rubber to be put on by a brush ?????
Years ago, at the time, the "Z-Club-International" still merited the name
"Club"....- there was sb, who built a "Bergbahn", very interesting project
and very well realized ! But this was without a cog-bar/cog-wheel, I think
the cars were moved by strings. Nowadays, the company "Railex" introduced
something similar even in "N" and "H0".
Thanks for the information about the poor flexibility of the M�rklin type !
Can anybody help me where in Europe to purchase the Peco flex track ?
....I enjoyed this afternoon and writing this email !
- Thank you all for exhaustive accounts on the maximum climbing grade issue.
The reason why I ask is that I am planning a very compact, multilevel
layout where almost all visible track is flat, while it is shifting levels
in hidden tunnels.
As I want the layout to be as compact as possible, and those mountains and
other hidden areas - especially at the ends of the layout - as small as
possible, I of course want the trains to climb to another level in an as
small area as possible. An as narrow helix as possible seemed the obvious
And, consequently, speed decrease is no problem, the trains are not visible.
There is another issue here, though. Starting up-hill. I guess, at the
grades I am discussing, this is impossible with stock locos.
I will also park trains in those hidden areas. Better keep those parking
areas flat or down-hill, I suspect....
This rubber thing on a pair of wheels is interesting. Who make and sell those?
- Snip, snip, snip......
There was a lot of good things said in this mail but I do not quite agree
about the flex M�rklin type track.
I have used it a lot but you have to cut the underside of the track on the
"outside" of the radia. Then it will bend easy. The advantage is that you
can make a very nice stransfer from straight to circular by keeping a part
fixed as it is and then cut where it bends.
The cutting is done between the sleepers on the outside of the radia.
