Work in 1.16 has continued in the month of February. Stacked train stops (sequences of stops for the same platform(s)) were not fully compatible with the new train logic in 1.16 and have been reviewed with a new, clearer set of rules which avoids some pitfalls. Train collision has been finally overhauled with a new system that performs real geometric intersection tests. And a new, very major technical capability for the game is introduced at the end of the post, but its release will have to wait for a future version. Read about it in the dev blog post:
