Can someone please tell me why DPU's (Distributive Power Units) are destined to derail when being produced by a portal?
(For clarity, a DPU is one or more locomotives placed in the middle or rear of a train to assist with power, control, braking, etc.)
In Trainz 2019 and T:ANE, everytime a DPU is placed in between freight cars or in the rear of a train, and the DPU and the leading locomotives have a different engine spec, one of them either pulls too hard or pushes too hard and tears the whole train apart, resulting in a derailment. In general, I've been able to dodge this problem by making sure the DPU's are the same locomotive as the one leading the train.
However, when I tell a portal to produce a train with a DPU, even if it has the same engine spec as the leading one, it still derails in the most absolutely absurd way possible.
As soon as the DPU is added, all the couplers are pulled away from each other so that there are like maybe three or more meters between every coupler in every car. Then the physics spaz out and one of the freight cars decouples and derails (usually one that's either coupled directly to the DPU or one that's near it) In some cases, multiple cars near the DPU derail and sometimes, even the DPU derails.
The physics continue to spaz out and the derailment causes the train to slingshot forward and backward in a silly fashion several times until the physics calm down.
The driver is disabled for the front locomotives carrying most of the train. They continue at 17mph until they reach another portal or train. (I haven't tested to see if they would drive off of a cliff yet.) This slow speed brings the line to a screeching halt.
The DPU's in the end of the train get the driver and follow along at an equally slow speed.
This has happened every time I ask the portal to produce a train with a DPU.
The consist in the example video above had 3 CR SD45's, 50 or more Bethgon (hopper cars), and 3 more CR SD45's. Without fail, it'll derail a random car between the front locomotives and the DPU's.
This happens with passenger trains, too if the cab car has an engine.
This also happens on high-speed trains with a locomotive on both ends. It always happens to the TGV Duplex without fail. With the AV01, it keeps derailing a random car in the middle of the train. The Shinkansen usually works, but sometimes at random, it'll derail the last locomotive.
So why does the portal have such a problem with producing trains with locomotives between two cars? Why does it have such a problem with locomotives on the end of a train? Why does it always derail two to four random cars in the consist whenever it tries to produce a locomotive in the middle or rear of a train?
