There is this? - https://www.justtrains.net/product/the-tee-trans-europ-express If not that, it's probably the closest you'll get on TS Classic
We also have the TEE Rheingold with the DB BR 103 on TEE Paint Scheme of Virtual Railroad Expertline. https://virtual-railroads.de/gb/train-packages-el/28-db-br103-tee-expertline.html
And also this amazing collection of Rheingold / TEE coaches through the ages, https://www.3dzug.de/product_info.php?info=p327_rheingold--.html I admit they are not cheap but the quality is absolutely stunning and if you are on a budget you can buy each set separately.
I would love to see the VT 11.5 in Train Simulator Classic; or its' Eastern cousin, the DR VT 18.16. The SBB RAm/NS DE IV is offered by Trainworx, and can be found here: https://www.trainworx.nl/product/sbb-ns-ram-tee/
