I have three questions regarding model trains. DCC, Track, Coupler conversion.?

Question by metalsuitman: I have three questions regarding model trains. DCC, Track, Coupler conversion.?
I have just recently gotten back into model trains. I guess I have some leisure time on my hands working here in China and have set up a layout which is a work in progress.

My first question is regarding track and how to determine size that a curve will take up. I know from the track I have which is standard but I need a tighter curve and wonder how to accomplish this. I have read there is flexible track but I am in China and do not know where to obtain it. I also think if I had the shorter curve track that might solve my problem.

My second question is regarding the new style trains and the mentioning of DCC which I know about but have not concerned myself with getting into. The question is: Will a DCC train work on a standard transformer run track? I assume it will but not sure.

My third question is: I have some older trains with the old style couplers in HO gauge. Is there a conversion to the new style?

Thanks for you help. Any other help is welcome.

My trains are HO Scale. I have an outside track which is a standard curve. I wish to run a track inside that with a tighter curve. I know they make shorter curve track and I suppose this will enable me to do this. I just don’t know the distance from one side of the curve to the other. Going to a hobby shop is not possible since there are none here in China that I have found. I just want to know the distance from the beginning of one side of the curve across to the other side of the curve. I can get the track but am building the layout and want to make sure I make the upper portion big enough to accept the curve.

The DCC is digital control and I do not have that. I want to buy an engine that says it is DCC ready and want to run it with a conventional transformer. Is there a compatibility problem doing that? Later I can do the DCC but for now just want to run the trains the old fashioned way.

How about coupler conversion to the new style. Wnat to convert to new style.

the size of the train set should be on the box it came in .
that will give you the size of the lay out .
from there you can use less of the track which should give you a shorter curve .you could also use a size whitch will put a turn in it the less track you use the shorter your curve will be .
you can obtain the track on eBay or at a hobby shop.
as for the DC that is the us transformer
the older trains should run on the same track as long as it is ho scale

HO Scale Model Train – Couple Questions regarding turns, grades?

Question by Infamous: HO Scale Model Train – Couple Questions regarding turns, grades?
Hello, I’m returning to model train crafting again, and I finally got a 13 foot x 9 foot in-door patio to work with, and I plan to turn at least half of the patio into a world.

Based on the size of the patio, I’m planning to turn the “large” sections of the patio into no more than 3-4 feet of plywood, leaving room in the center to stand and be able to reach across (since my arm length is about 2 feet). Some sections will have multiple heights (bridges, cliffs, etc).

Based on that description, here are a few of my questions;

1) How much feet (or maximum grade) will be needed to elevate the train for every 6 inches? (In other words, how long does the grade need to be to accomplish going up for 6 inches?

2) How much space is needed to accomplish a 180 degree turn?
3) What about a 90 degree turn?

4) Is there any wiki or online resource for getting these measurements or percentages?

Thanks in advanced! 🙂 This is a fun hobby.

Check out some of the model railroading sites and forums, or there are probably books on model railroading at the library.

Here are some possibilities online:

Question about SPSS regarding numeric/string?

Question by LibraryFan: Question about SPSS regarding numeric/string?
I have a question regarding the SPSS program. Let me explain my usage of it. As part of my job, I do data entry of surveys and send our client an Excel and an SPSS file of the same data. I do not have any training in computer software, nor was I given any in-house training at work regarding how to extensively work with SPSS. My usage of it has basically been following the example of how other people at my job have used the SPSS program.

I do my data entry in Access, then perform a regular export to Excel. In transferring data to SPSS, I just set up my SPSS form to match my Access query using the variables tab, then copy and paste the data from Access to SPSS (again, this is just how it’s been done; a better way probably exists).

My question is regarding the rounding up of numbers that occurs whenever you put a “.5” in a cell that has a “numeric” type. It automatically rounds the half up to the next whole number unless you include a decimal place. For this client, we have never included a decimal place, as most of the data is the “excellent to poor” rating scale. One question, however, regards a number of hours. Some survey respondents reply with halves (e.g., 6.5 hours). As the data entry operator, I have been rounding these up because I knew that the SPSS would automatically round them. Lately, though, our client has been on our backs about complete, accurate adherence to what has been recorded on the paper surveys. I believe I addressed this several years ago to a supervisor, and they said to round them, but I’m not sure if this came from them or from a communication with the client. I’m actually kind of nervous about broaching the subject with the client, as they’ve been touchy, had an issue with my data entry a few months ago and I don’t want them to lose faith in our company. It’s just this one question about hours that’s worrying me, but I don’t want it to bite us.

Anyway, what I’d like to ask someone more in the know about SPSS is whether I could change the data type for that question to “String” and have that be fine. It would allow me to enter single digits as well as halves. I do not know what our client does with the data once they get it, how they process it. Does the data type in the SPSS form have to be “Numeric” for it to process as a number, or can data entered as “String” also process as a number? I’m asking this because I’m wondering whether I can just change the data type without telling our client and have it process on their end without any hitch. Can someone give me an answer to this?

1) SPSS does not round numbers when importing. If your Access field contains a decimal or has a decimal setting, that should be preserved in SPSS. After importing, go to the Data Editor Variable View and see how many decimals are set for your numeric variables. There is a different between the displayed values and the full precision values that are used for computation.

2) If you import a string datatype, SPSS will create a string variable. If the contents are numeric, it can be converted to a number in a variety of ways, but if the values are numeric, it is better to use a numeric type in the database.

3) SPSS can read Excel files directly, so unless you are using Access to restructure the data in some way, you might as well import it directly into SPSS from Excel.
