Choice of prototype

[EVGEN]

A good choice!

You'd better tell me how your father was able to buy the necessary drawings? Are there specifications (a list of drawings) in which the numbers of the required drawings are reflected? At me one detail could be uttered in one of 2-4 drawings. Which to choose? Without a specification, there is complete confusion.

I'll choose option, at Y-5. Looks gorgeous, like a hippopotamus from M & M, like a shaggy bear from the den, gnarly.

Evgen,

I am curious why you selected 10 1/4” gauge track for your RR? Is this common in the region of Europe where you live?

Also, have you considered a larger gauge? Say 12” or 15” gauge? The larger gauges are often more suitable for commercial operations, such as giving rides to the public. Here in the US, now days, 15” gauge seems to be the most popular Park Guage track size.

Good luck with your project. Building an articulated in any scale would be a fun and rewarding project.

Evgen,

have a look at this archiv.....

come in and find out......

In my region there are no garden railways. Therefore, I have the right to choose any scale. At one time in the Soviet Union there was one railroad at a scale of 12 in. One for the whole country. russians, for example, actively use 12 in. For a track of 1524 mm, a scale of 12 in gives a scale of 1: 5. This is a beautiful scale. For the collegium in 1435 what is the scale? 1: 4.7? 15 inis too much.
Maybe I should pay attention to 12 inches. The matter is that I would like, that my locomotive could build modellers from the different countries. After all, first I will develop a set of drawings for the entire model. The 12-inch scale is still more common in the world.

It's naive. Do you think I did not visit this site?

A good resource. A lot of information. All information is piled into the heap.But every locomotive is unique. When I collected the drawings for the English A-4, I received from the archive a specification for each particular locomotive. In the NWHS on a question about the specification, employees shrug their shoulders. They recommend studying photos.

Evgen,

we did it with that....

And yes i think you havn't search this side....so if you...no more questions about drawings nesscesary.

No more informations needed you can start.
We build the 3 loco with those Drawings, i didnt see the Problem,sorry

In May i visited the USA and a modell builder ,he also builded an A and J class with drawings of the NWHS.

No problems, just do it Evgen

Maybe I missed something. Unfortunately, my English leaves much to be desired.

If you say that everything is so simple. Help me figure it out. What should I do. I'm interested in Yu-4 number 2080. The condition for 1956 (maximum pumped machine). http://www.nwhs.org/archivesdb/detail.php?ID=145568

A few examples:

1. I'm interested in the detail drawing Bottom Draw Fulcrum. There are two drawings:
http://www.nwhs.org/archivesdb/detail.php?ID=50523
http://www.nwhs.org/archivesdb/detail.php?ID=150850
Which one should I choose?

2. What was the construction of the joint?

2. What cylinders should I use?

Evgen,

later more,have to work.

EVGEN,
All the best to you with this project. The mallets were always a fascination and the Virginian Railroad (absorbed by Norfolk and Western) had many of them pulling and pushing coal trains. Massive!

This was one of their largest locomotives: (The 800 met with disaster when its boiler exploded)

[EVGEN]

Chris. Good. Then you must be aware of the matter. There are drawings with the same number, but different Revision Date. For example, the following drawings are available:

http://www.nwhs.org/archivesdb/detail.php?ID=161736
http://www.nwhs.org/archivesdb/detail.php?ID=52743

1. What does Revision Date mean?
2. Are the drawings equivalent or do they have differences?
3. Drawing: http://www.nwhs.org/archivesdb/detail.php?ID=52334 - which means Style No. 3F ???

I've done a little bit of research in the N&W Archives. There are a lot of parts that will have two drawings, and earlier one and a later revision. The earlier drawings are of the original parts as the locomotive was built. Later revisions seem, to me, to be for repair/replacement parts when the locomotives needed servicing or when doing an upgrade to a class of locomotive.

For example: The N&W M-class 4-8-0 has early drawings (1906) and later ones (1925). The early ones are for the locomotives as-delivered. The later ones must be for repair and replacement parts, since no new M class locomotives were built for more than 10 years prior to that. I had heard that a few of the iron wheels on some of the M, M1 and M2 locomotives had cracking issues, which would explain why there were two drawings, an earlier and a later. Same for the lead truck wheels. Some of these locomotives lasted all the way to the end of steam on the N&W, so they had to have been shopped many times over their lifetime.

Hi Guys,

i think pontiacguy is absolutly right. Same thoughts i have many times during watching the drawings of the J.
The J had 3 types of engine trucks , i always choose the later versions, because of the reasons pontiacguy told us.

Evgen is it your first try to build a locomotive?
Your shop must be very big and your machines also, how could you handle the sice of the parts?

Chris
