Ben outta town haven’t been able to download all the new updates but,the Amtrak cars only couple on one side,is the anyway to differentiate between front or back when throwing them in the rerailer
The superliners only connect in one direction on purpose, as when you look at them, there is a rubber gromet on one side that is supposed to seal to the unit behind. Just like in real line. So when putting them on the rerailer, make sure that all the ends with the black rubber are pointed in the same direction, and make sure there is no spot where the black rubber is facing the black rubber, or else it wont connect
