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.
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.

Zeller Rollenprüfstände und TC 8
Für die Prüfstände der Firma Marion Zeller gibt es eine Option für die verschiedenen Maßstäbe. In der Online-Programmhilfe findet sich dazu folgender Eintrag:
ZellerDiameter
Setzen Sie diesen Wert auf xxx, wobei xxx den Durchmesser der Rolle angibt in Hundertstel-Millimetern. Die Voreinstellung ist ZellerDiameter=593, was für einen Rollen-Durchmesser von 5,93 mm passt.
Die folgenden Werte zeigen Beispiele für die verschiedenen Prüfstände der Fa. Marion Zeller:
- 610: 6,10 mm für Spur H0, 0 und 1
- 475: 4,75 mm für Spur N
- 580: 5,80 mm für Spur TT
Beispiel:
[Connections] ZellerDiameter=475
Die Firma KPF-Zeller hat für seine Speed-Cat einen neuen Drehgeber herausgebracht. Der Präzisions-Drehgeber hat die 4-fache Auflösung gegenüber dem Standard-Drehgeber der Speed-Cat und soll ein präziseres einmessen bei geringeren Geschwindigkeiten ermöglichen. Daher ist der Wert der Voreinstellung (593) nicht mehr zutreffend, sondern muß durch 4 geteilt werden:
Beispiel:
[Connections] ZellerDiameter=148
