About the position detection/calculation in JMRI:
Does it JMRI can calculate the position of each vehicle of a train??
Like, for example, telling that a train begin at cm X and end at cm Y, with couplings
at cm A, B, and C??
About TrainController, I've searched but found nothing about train
position other than telling which block is occupied. Do you have more
information??

From what I I know about JMRI, it will do the things you ask for, however there a very steep learning curve, in my opinion and you need to
understand programing to get the best results.
A better solution, in my humble opinion (still with a learning curve, but much less than JMRI) is to use TrainController (Gold Version), apart form
automation it is very easy to draw your layout in TrainController.
Another advantage to TrainController is that there are very good YouTube videos available from several authors that will take you through the
process of learning how to use TrainContoller.
I understand that the price of TrainController Gold Version at approximately US$800+ (less costly versions of TrainController are available at
lower cost and functionality), will be off-putting for some people. However if you have a DCC based train layout your investment in DCC
technology will probably be in the several thousands of $. For example the price of x2 well equipped high end loco¡¯s with sound can cost more
than TrainController.Gold
I am sure that others will have varying levels of viewpoint than mine.

Hello,
I have a few questions.
Does JMRI can deduce the precise location of a train from its speed, it's size and a few object detectors ?
If yes:
* With which precision ?
* Does JMRI can use train precise location to automate the maneuvers, including uncoupling and train formation ?
Do you know of other software than JMRI who can do that ?
For my diploma work for engineering, I need to develop a system that can measure, or deduce, the precise location of a train, with a
precision of 2-3 cm.
Then, using this location, the system need to automate the maneuvers, including uncoupling and train formation.
But before developing this system, I need to document what's already exist in the field of model making. And then found a new way of
doing it.
I'm only allowed to develop something that nobody have already done.
For the detectors, it's seems that model makers have already done every possibilities.
Including using 2 objects detectors to measure speed (and JMRI already have a speedometer).
For positon deduced from other data, I have seen that JMRI already have a Train Tracker [1].
But, as I have only used the Decoder Pro until now, I don't know if the Train Tracker correspond to what I'm asked to develop or not.
Best regards.
PS: If my diploma work can be done, I plan to release the result software and hardware as free (as in freedom) software and hardware.
And all the documents in similar licence. And if it implies modifying JMRI, I would be very happy to send my modifications as
contribution to JMRI.
