Update 2 (2019-12) Notes and Comments in English
My effort to translate and comment on the Tomix documentation for the second (2019-12) update to the TNOS system. Use it in conjunction with the Tomix document itself:

Tomix TNOS Keypad Cheat Sheet (English)
My handy, updated one-page PDF "cheat sheet" in English to help you use the Tomix TNOS System's control keypad. Print it and keep it by your layout, like I do.

Tomix TNOS Operating Parameter Sets and Customization of Sets 1-10
A one-page PDF document I created in English, detailing the Operating Parameter Sets used to tailor the Tomix TNOS System to the differing operating characteristics of various train models made by various manufacturers.

Notes on the TNOS SD Memory Card (English)
A short PDF file containing my notes in English on the TNOS SD Memory Card, including the SD card itself, its folders and file types, and card updates and how to perform them.

Tomix TNOS Command Language (TCL) Notes (English)
This PDF file details the various commands that make up Tomix TNOS TCL. This command language allows users of updated TNOS systems to write, save, and run program files that move trains around an existing Layout Plan, one train at a time.

Sample Tomix Command Language (TCL) Files to Study (with English Comments)

Sample TCL File by Tomix (Layout Plan 1, TCL file 250)
One of three sample TCL files released by Tomix. I have translated and added English comments in this file. View it with a text editor like Windows Notepad. I do not know of any online video which shows this file in operation.

Sample TCL File by Tomix (Layout Plan 2, TCL file 250)
The second of three Tomix sample files. As above, I have translated and added English comments in this file. I do not know of any online video which shows this file in operation.

Sample TCL File by Tomix (Layout Plan 3, TCL file 250)
The third Tomix sample file, with my translated and added English comments. I do not know of any online video which shows this file in operation.

TCL File by Youtube Content Creator ひぐらし (Layout Plan 1, TCL file 249)
This TCL file is shown in operation on Youtube: www.youtube.com/watch?v=StuG6g4cCTk
The file itself is helpfully provided by the author in the comments section for the video. I have translated and added English comments to the file.

TCL File by Youtube Content Creator ニート店長 (Layout Plan 90, TCL file 101)
TCL File by Youtube Content Creator ニート店長 (Layout Plan 90, TCL file 102)
TCL File by Youtube Content Creator ニート店長 (Layout Plan 90, TCL file 103)
These three TCL files are all shown in operation in this Youtube video: www.youtube.com/watch?v=67ZeUy7bQ-g
The files themselves are helpfully provided by the author, in the video itself and in the comments section. I have translated and added English comments in these files. If you watch the Control Unit display carefully, you will see the TCL file numbers appear. TCL file 101 appears to begin at 1:05, but then seems to be interrupted. It appears to run completely from 6:14-8:37 in the video. File 103 appears to run at 3:20 in the video. File 102 may not exacly match the video operation, since some of the commands in it are "commented out" (with a leading semi-colon) in the file provided. This author has also uploaded other informative videos demonstrating Automatic Operation sequences for TNOS Layout Plans.

Tomix TNOS Layouts We Would Like to See

Click here to see a variety of layout concepts that I have devised for possible TNOS Layout Plans and Automatic Operation scenarios. They would add a lot of variety to the ones already available, and many are ones that railway and tram modelers around the world would find very desirable. While I have sketched out the ideas, it would be up to the folks at Tomix/Tomytec to do the programming and release them in future TNOS updates. I hope they come across these concepts and see the value in them!

JNS Forum
A small but hardy bunch of English-speaking Tomix TNOS users puzzle over and discuss the system on the JNS Forum, a Japanese modelling and Japan Rail Enthusiasts forum. You can read our discussions and contact us there, in the "DCC, Electrical & Automation" topic area.

Tomix TNOS with Kato Unitrack
JNS Forum member "Yavianice" is documenting his use of the Tomix TNOS system with Kato Unitrack, proving that there's no reason for Unitrak users to remain envious about the TNOS system.
