If you double head you may get 3% or more, assuming you have curves, but
it is kind of "check it out" first on YOUR equipment. On a straight
away with VERY SHORT trains you MIGHT get 4%, but that is stretching it.
1% is 1 unit up per 100 units horizontal 2% = 2 units up per 100 units
horizontal etc. ...don

Which model with what attached and what kind of track ?

I've done something of the order of 1 in 7 reliably on a steady curve
with short trains where there are no points on the sharp bits. Since I
was trying to model mountain railway practice (loco at bottom pushing
one or two wagons only) that was fine with the fairly light Märklin
wagons.

I wouldn't try above 1 in 30 by choice with a longer european train.

Downwards they'll do vertically, all too happily 8)

hmmm.... there is a tool that does measure the grades of a layout.
It's the Maerklin car #86191 It shows directly the grade in %. This
car is intended to be a item for members of the insider club, who are
a member for 5 years if I remember correctly, but I got this car at
Ebay Germany, where it shows up very often.

Another way would be to put one of those small levels which you can
hang on a line for simple construction work on a flatcar. But on the
level of this kind that I have somewhere in my toolbox, there are no
numbers for the grades. It shows only if something is level or not. So
you would have to mark the numbers before you use it on your layout.

I also got one from Ebay last year. It is cute, but I find not too
accurate as confirmed by turning it 180 degrees on the track. I think a
laser level set on the tracks with a reading off of a wall a few feet
away might be more accurate.

but only if nothing is in the way of the laser beam to the wall. In
those cases I think that the Maerklin car is good enough, just check
out by putting it on the track in both directions. At my car the fault
was less then 0.5%.

Hi Uwe:

BTW a 0.5% out of 2% is a pretty substantial error percentage wise but
for what you are really doing I agree the Marklin unit is O.K., plus it
is kind of nice looking. Just think if it were full of beer-I saw some
photos the other day in one of the current train magazines with 14 tank
cars each holding 10,000 gallons of Coors Beer. Actually I just use
Woodland Scenics foam material that has the grades built-in, and
purchased the Marklin Z car because no one else bid on it that day. To
me, Woodland Scenics is the easy way especially if you are building a
curve. ...don

Figuring out grades is pretty easy, just divide the height by how long
it takes to get there.

Lets say you wanna go up and over another track at 2" higher than the
lower track. Now the start of the grade is 8 feet away. 8 feet is 96
inches.

2 divided by 96 is 0.020833333333 now move the decimal over 2 places
and you end up with a 2.08% grade or just call it 2.1%

Now if you want to put a riser under your roadbed every foot, just
divide the 2" by 8', you will get 0.25, that is 1/4" So your risers
would be.
0
.25"
.5"
.75"
1"
1.25"
1.5"
1.75"
2"

This is just an example.

you mean as in:

If you can't do it in Z it's impossible anyway, and if you do it,
you're a wizard.... ;-))

> for what you are really doing I agree the Marklin unit is O.K.,

you're right 0.5% out of 2% is 25%... but out of 4 it's only 12.5%...

...well now, since we are into % anyway I like to have a 40% (or 80
proof) anytime while watching my trains... ;-)

...for getting serious again, I would always recommend to test any
grade with the rolling stock that is intended for the use on that
layout.

lately there was a auction at EBay with a set of glas tank cars
labeled for different beverages. The Whiskey and the Rum were still
full, but one labeled for beer was empty... :-( ... ;-)

and sorry, but I don't know Coors... I always had a Miller time when
in the US... and Coors is hard to get over here anyway :-)

It wasn't very hard to build the grade (including curves) in plywood.
The main thing is, not to start the grade with a new piece of plywood.
I did cut the track base out of the sheet, and then started to bend
the grade up after I fixed a good part of the track base level. This
way I also did get a very smooth change from level to grade.
