I really want the old Minecarts "train" mechanic back

The new Minecart Improvements Update is pretty wonderful, the new Game rule is good, everything About it is good, except for one thing. I always loved to make Trains with minecarts and it's were I form a line of Minecarts, push the one in front, it hits the one behind and starts moving forward and the same repeats until all minecarts are moving forward following closely behind each other in a single direction, forming a Train. However the Minecart Improvements update removes that mechanic, and this is actually a huge problem for my Minecraft Railfanning because i play on a Nintendo Switch, and there's no experimental toggle for this or a way to revert the Game Version. I even made so many maps of real Railfanning locations to make Railfanning Videos by using that old mechanic part of Minecarts. But now I can't make those trains anymore, and the tutorials I made for people to make those trains are basically useless now. I love the new Game rule, but I heavily dislike this part of the Update for 2026. I even put mobs in them were I push the front one, and the lead mob looks like a Locomotive while the Minecarts following behind look like Rail Cars. In summary, I really want the Old Minecart Mechanic back really bad. I want to make those Trains again, and I think other people want that to especially my friend on one platform named "AmtrakWolfMinecraft2026" who uses the same method. What I mean is, I want the Old Minecart Physics back to do that thing again.
