Calibrate the locomotive with the roller test bench

Physics - Roller Test Benches

First and foremost, physics: Even with load-controlled decoders, the physical properties of the vehicles must not be ignored.

On the roller test stand, the physical mass/inertia has virtually no influence on the measurement result, since the locomotive mass (i.e. the locomotive weight) does not have to be set in motion on the test stand.

On the measuring track, however, it is different: Here, the inertia of the mass must be overcome during the measuring process so that the locomotive can even start moving in the first place.

Therefore, it is reasonable to assume that the locomotives run faster on a roller test stand than on the rails, even if everything is identical from an electrical point of view.

TrainController from version 9

From version 9 onwards, TrainController offers a general, hardware- and manufacturer-independent interface that can be used conversely by the various measurement systems.

• Mr. Freiwald writes about this in this post:

Since version 9, virtually any roller test bench and other measuring system that offers a PC interface can be used for calibration. A return to limiting support to just a few roller test benches, as in version 8, is certainly no longer practical.

However, we no longer expend a great deal of effort for each individual system to program a special adaptation to the respective PC interface of that system.

Instead, we take advantage of the fact that manufacturers of such systems already have (or are required to have) software that fully operates their own PC interface and can display measured values. Without such software, the manufacturers would not have been able to test their own PC interface before releasing it.

Starting with version 9, TrainController offers an automated measurement procedure where measured speeds are copied to the Windows clipboard during the calibration process. Manufacturers of measurement systems simply need to extend their existing software to write the measured or displayed values ​​to the clipboard. This can be done with fewer than 10 lines of code. And if you don't know how, you can find countless code examples online in all common programming languages.

Windows clipboard

Silvio Richter describes in the forum:

What is often forgotten and/or overlooked is the fact that Windows no longer has "one" Windows clipboard, but several in parallel.

Die Kommunikation mit TrainController läuft über diese Zwischenablage.

In Windows ist die Zwischenablage so einzustellen, dass es nur eine gibt. Die Suchmaschine Deines Vertrauens gibt dazu Auskunft.

µCon Railspeed from TC 9

µCon Railspeed definitely works with TrainController 9. You also need to download the "Railspeed Data Copy Tool for TrainController 9 Gold" (RDCT) software from LSDigital's download section [1]. This tool runs alongside TrainController and receives the data from µCon Railspeed, copying it to the Windows clipboard, from where TrainController then retrieves the data.

Zeller roller test benches from TC 9

KPF-Zeller's roller test stands also work with TrainController 9. You also need to download the "SpeedCat PLUS" software as a ZIP file from the download area on the KPF-Zeller website and install it alongside TrainController.

TrainController to Version 8

TrainController 7 and 8 support the calibration of locomotives using roller test stands. However, a few details need to be considered.

RAILROAD.INI for TC 7 and 8

TrainController itself does not offer any configuration options for the roller test stands. From TrainController 7.0 F3 onwards, these settings can be configured in the RAILROAD.INI file. However, depending on the Windows version used, this file is not always easy to find.

Windows 7 with active user accounts:

C:\Users\UserName\AppData\Local\VirtualStore\Program Files (x86)\Railroad & Co.80

Windows 7 without user accounts, older Windows versions:

C:\Program Files (x86)\Railroad & Co.80

A corresponding entry must be added to the [Connections] section.

Zeller roller test benches and TC 8

The test benches from the company "Marion Zeller" offer an option for different scales. The following entry can be found in the online program help:

ZellerDiameter

Set this value to xxx, where xxx represents the diameter of the roller in hundredths of a millimeter. The default setting is ZellerDiameter=593, which is suitable for a roller diameter of 5.93 mm.

The following values ​​show examples for the various test benches of Marion Zeller GmbH:

610: 6,10 mm for gauge H0, 0 and 1

475: 4,75 mm for gauge N

580: 5,80 mm for gauge TT

Example:

[Connections]
ZellerDiameter=475

KPF-Zeller has released a new rotary encoder for its Speed-Cat system. This precision encoder offers four times the resolution of the standard Speed-Cat encoder and is designed to enable more precise measurements at lower speeds. Therefore, the default value (593) is no longer valid and must be divided by 4.

Example:

[Connections]
ZellerDiameter=148
