From 6.10.1 Acoustic, shock, and coupled acoustic-structural analysis
"Projecting and storing the acoustic coupling matrix during the natural frequency extraction is also available for the Lanczos eigensolver based on the SIM architecture."

Excelent! My mistake. [afro2]
Keep the +1 because if you have 200 increments, incrementNumber it's 199 and range(199) will give you [0, 1, ... , 198]

odb = odbAccess.openOdb(path=Odb)

As I could see, the time between the original step and the time of the new one are equals. Maybe you are comparing the increments.
The unsolved problem then is the 'index out of range' error. I recommend you to try:
- The easy way is to replace the variable 'nFrames' by an integer number like...
I revised the code and found some mistakes but nothing related with the indexError. Also I added a +1 at the for loop to complete all the frames. About the re-ranging of the time domain I did't see what you said. I send you some screen shots:

New step:

Hello. Just replace 'odbFileName.odb' with your odb file, and 'stepName' with your step name. Execute this script setting the Work Directory of Abaqus CAE in the same path of your odb file.
Enjoy!

The same loads and BC should be applied to the submodel. To transfer the displacements from the global model to the submodel use the BC that Mustaine3 indicates you.
Check page 24 for an example:

I model wear once. I could reproduce the simple model of the next thesis:

Here there is a code for the subroutine. Everything is carefully descripted. It is a great work.
If you are starting to use UMESHMOTION, I advice to you to start...
Something usefull is to debug your code line by line. You can do this from the abaqus PDE. Or also you can copy and paste line by line of your code in the Kernel Command Line at the bottom of the window of abaqus CAE (you can see it cliking on the >>> icon).
As Mustaine said check your unit system. The structure units are in mm and the rest of your parameters are in m. Your structure have 190km!

Another thing that you can do is to analyze COPEN... If the variable CPRESS=0, COPEN should be >0 (Not in contact yet). If this statment is false, there is something strange!
It is impossible to answer that, because your question is very inespecific.
Have you ever used abaqus?
What are you trying to modeling? The wheel-rail? The ground? The whole train?
And... what are you looking for? Fatigue? Vibrations? Static Stresses?
Your question is very vague... but I can tell you this:
There is a GLOBAL MODEL and a SUBMODEL. I suppose that you are asking if you can use a different step on the SUBMODEL. It is a posibility if you have the specific purpose. You can make a dynamic step in your GLOBAL MODEL and for some...
I've been using this .bat:

Body force have a different definition than gravity. I suppose that you account this difference.
I have a few possible causes for the limited displacement of the spine:
- Maybe you have a problem with the units (units of loads or materials).
- I don't know anything about spines, but maybe the...
What kind of analysis are you doing? Static, dynamic?
To start i will do a static analysis. If you create the load "Gravity" , you should create the BC to restrict the movement of the spine.
The disc is another part? how is it conected to the spine?
