yo I heard that with update 4 there will be train signals and collisions the room is true, we never, said that, we're going to be putting out trains and collision on update four but we have said that we will just, train signals and collisions but we have said that we will do we want to do signals and we want to do collisions on trains, and that when we do it we want to do both at the same time and not one before the other, that's what we've said on train signals and collisions and we don't know exactly when that will happen
