No it doesn’t. Doubling the number of trains doesn’t double the number of vehicles if each train is half as long. You don’t know what you’re talking about here. Longer trains are harder to handle and end up with dynamic forces down their length that are less visible to the drivers. Long enough trains can lead to severe in-train dynamics that the drivers aren’t even aware of which in turn can also produce dangerous vertical wheel-rail contact force scenarios that cause derailment risk to skyrocket.
