So, basically, it’s a function similar to one of the automatic transfer station functions (where one train waits until the other arrives, then the first one moves), with the difference that here we are dealing with trains on the same track.
The only problem with all Plarail stopping systems is that the train looks strange after it suddenly stops at the stop, and the carriages almost always move sideways, so it looks like the train has had some kind of accident, not a stop. In this sense, only the new grey Plarail Real Stop Track, due to its specific design, provides a slightly better experience.
