Just out of interest can you point to some internet references to demonstrate where an auxiliary tender was used, and how coal and water were transferred between them?
In regard to your question about setting the physics for it, all the tender volume information (coal and water mass) is set in the ENG file and not in the tender WAG file. So in principle the auxiliary tender would be set as a standard WAG file, and the capacity values entered in the ENG file.
The only challenge with this approach may be in regard to the new freight animation functionality currently being developed for the tender coal load, as I suspect that it may not differentiate which tender is being used to fuel the locomotive at a particular point in time.

The coal bunkers are either plated over and store locomotive parts for over the road repairs or are cut down and removed making way for more water storage.
A very small number of aux tenders had the coal space converted for oil fuel storage for locomotives that burn oil. Although I can't think off hand of a good example right now as this practice is extremely rare.
The Union Pacific uses two water tenders from earlier class 4-8-4 locomotives. They also serviced as fuel tenders for the gas turbines before they were retired and scrapped.
The NKP 765 has a 15,000 gallon aux tender.
Milw 261 has a 25,000 gal aux tender.
N&W 611 has a 25,000 gal aux tender.
Some internet aux tender information.

If the car is defined as Type (Tender) and there is no ORTSfreightanim block within the .wag file of the tender, the new ORTS freight animation does not influence this second tender.

I am interested in figuring out if extra water can be added by suddenly coupling a aux tender to the main locomotive tender. Looking to have atleast two states tender 1- main tender. tender 2- aux tender. Right now MSTS can only read tender 1 the main tender.
Also locomotives like the gas turbines had their fuel in seperate tenders. Yet, MSTS does not have the option for tender operation in say diesel mode.

Regarding the auxiliary tender question, I can add another example where these were used. On the CB&Q Sterling branch they used a water car with the steam locomotive because many of the water facilities were not maintained in later years. In this case the auxiliary tender was simply a tank car modified for auxiliary water car service.
Here's a picture of CB&Q ten wheeler 919 in Cheyenne being serviced with her tank car / water car coupled behind:

I believe the Scotsman is one of the locomotives I have uncoupled the tender and had readings for fuel and water go to 0.
If we could get IsTenderRequired 1, 2 or 3 option then I could have the main locomotive tender and up to 2 aux tenders like C&O 614 used during her ACE 3000 testing in the winter of 1985.
Edit, I just confirmed the default Flying Scotsman fuel readings all go to 0 if the tender is uncoupled from the locomotive.
