Andrey

Measurements for PIKO locos are here: http://www.3smr.co.uk/readytorun.html

Unfortunately the BR151 is not the same as any US loco that I am aware of. Having a truck with the longer distance between outer - middle axle and the shorter distance between middle-inner axle is not US practice.

The Hercules chassis is exactly correct for EMD FP7 and FP9. http://www.rockisl.com/cgi-bin/display. ... 1&n=402-2a

Again, a common locomotive and a good choice for a modeller. The 'P' in FP7 means it was a bit longer as it had equipment for heating passenger trains, but also able to be used for freight.

What loco is the Tillig bogie in your frame from?

Great etching work, by the way.

Thanx! ((^

I use tillig a new «Nohab» distance between 3 axels on one bogie it the same or have so small different in length … well I hope that it is already clear that we can make a distance between bogies exact what we need by using an own frame.

Ben please can you give me for example some distances between 2 and 3 axels on one bogie?

That all I need to star searching here in Rus.

I’ve serf some links you gave me an collect this interesting for me (and I hope fore you all) lock ) there are 4 and 6 ax.

B.t.w. I’m completely forgotten how to calculate this

6’-9” ½
1” = 2,54 centimeter…

Help! (-:

Hi Andrey,
I was wrong , the UP diesel 5042 is an SD50 like Ben said. It has a different number now, the number is used now for an SD70M.

There are a few basic styles of two axle trucks. EMD made all the GP's with the same style trucks, called Bloomberg truck. they were used on the GP7 through the GP60. These were the same trucks as the F3, F7, F9, FP7 and FP9 and the BL2. It is spaced 9 feet (2743mm) between axles, all had 40 inch wheels (1016mm). There are some differences in the side frames, the bearings and springs, etc.. but they are all pretty close.

General Electric also uses a truck with a 2743mm spacing on their newer four axle locomotives, like the B23-7, B30-7, C40-8 but they are a different style of truck. The older GE locos (U25b, U 28B, U30B, etc..) used a truck that was 9 feet 4 inches, 2845 mm. The same truck was used on Alco locomotives, like the RS1, RS2, RS3, C424, C425, etc. All had 40" wheels, like EMD.

There are more kinds ofthree axle trucks. EMD used at least two types, the older ones (SD7 through SD45) are spaced at 2070mm by 2070mm, total 4140mm. The newer EMD "Dash 2" (SD45-2, SD40-2, etc) are a little different- 2022mm x 2127mm, total 4149, only 9mm differnce! But they look different.
GE and Alco used several different three axle trucks, The older GE is 2019mm x 2121mm (U-33C, U36C), The newest GE is 4013mm total but I can't find the spacing.
I found one Alco (C-628) that was 1702mm x 2108mm, but that is an older locomotive. Alco stopped building locomotives in the US in the 1960's.
There are a few others, I'll keep looking!

Help! (-:

OK!
1' (one foot) is 12 inches (12"), 9"1/2 is 9.5 inches, so
6' x 12 =72 inches,
72+ 9.5 = 81.5 inches,
81.5 x 2,54cm =207 cm or 2070mm

So we have now that a model bogie shod hav a distance between axels from 17,25 mm up to 22,85.

As I understood for this lock
http://prr.railfan.net/diagrams/PRRdiag ... &sz=sm&fr=
there is a Tillig bogies with driving shift and engine!!!

All I had to do is just to build my own frame – that is absolutle not a problem because I gonna do another Rus lock based on this bogies but a frame will be mine!

If I right – may be we will try to build an EF-36 - EMD SD45 ??? (has it been used by UP RR ?)

Thank You for all, and also to star using in your messages metric system!!

I didn’t get this: ”… are a little different- 2022mm x 2127mm” does it means O– 2022-0-2127-0 (0- is a wheel)?
Or it means distances of two locks you’ve been talking about?

2022mm - 15,85 in model
2127 mm – 17,725

For all of that sizes we have
Also TILLIg
And this
And this has(Tillig bogie – my frame):
http://www.palich.com/gallery/rail_chme3/IMG_5510_s
16,5 mm (I was mistaken before)

For me +/- 0,5 – 0,7 mm is not a big problem.
What you say guyes?

Hi Andrey,
The first question, yes the axle spacing is not even. They are spaced just as in your diagram (center of the axle to center of the axle), it is farther from one end axle to the middle axle than the other end one. On the older EMDs, the spacing is the same, like on your UP SD-45 here-
http://www.rr-fallenflags.org/up/up2783atb.jpg

And +/- 0,5 or 0,7 mm is good- we can't be too picky yet!

I forgot-
The SD45 is a favorite locomotive of mine! I have a book with more information and good drawings I can send to you if you want them.

If so - let’s try to build this magnificent locomotive!!!

I think I’ve found (of course with your help) detailed pix of the roof e.t.s. but of course this is nothing without plans.
I’m ready to start to build my first US loc in TT and think that will be a first modern model loco in United States?
At the moment I’m finishing this locomotive:
Proto:

Computer model:

It’s not a problem to build them it parallel.
