Consist of locomotives struggles to pull a train after isolating an unused locomotive

So recently a new version of JR Train Effects Library came out and I noticed that this new version offers a start up shut down feature to isolate one or more locomotives from a consist to recreate a Dead in Tow aspect for locomotives being power shuttled to a location on a freight train. I've noticed that whenever I isolate a locomotive such as an SD40-2 from a consist of 2 or more GEVOs or ACes. The rest of the locomotives can barely get the train up to 1 mph. But then when I start up the isolated unit. The train is able to move just fine. Is this just Trainz being Trainz or is there something wrong with the new version of the script library to cause this?

I have a feeling it's Trainz doing what Trainz does best. Have you tried releasing the brakes?
 
That was my thought as well. Just turning the engine off likely doesn't release the loco's brakes or put it in Neutral. In the real world that isn't the behavior I would expect.
 
I finally had some time to sit down and try to reproduce this. I didn't come across anything unusual when running a random consist of modern locomotives I chose with a hefty unit train.

Here you can see I have 2 of 5 units online. I was still able to get the train up to track speed on this flat section of track, and all of the numbers seemed pretty good.


I tried again with what you described to see if that made any difference but was unable to come up with anything close to your description. is there anything else happening at the time?

I've recorded a demo video with 2 SD70ACes and one empty well car. I've isolated the trailing unit in this test and can confirm the brakes were released. Even with just one car, the lone locomotive was unable to get the train moving until I put the trailing unit into "Run." After that it started moving perfectly fine.
 
Its DCC mode...

This was never intended to be used in DCC mode in the first place nor can I think of a reason to do so. This game just doesn't work that way in DCC. The issue is DCC mode uses the lowest accel force in the consist as the maximum. When you isolate a locomotive, the maximum becomes 0. A DLS update of the spec will be issued to hide the problem, but isolating a loco in DCC mode will have no other effect except that it will not throttle up, and wont do external things like animate dynamic brake fans, so essentially only audio/visual effect in this mode.

Hi Justin, I would like to clarify something about latest TFX v 146d the start up shut down feature to isolate. When a locomotive is set isolated should it be dead and no engine sound playing in game?. I have observed in video above the second Locomotive appears be dead and not seeing any smoke from smoke from exhaust playing engine sound until it is set to "run" and its playing the "engine startup".
I have noticed when isolating a Locomotive from consist the engine sound is playing but just in idle while the first Locomotive is acting as normal when throttling up or down. can you please clarify?.
 
i am not seeing this feature at all in my TRS22PE Steam Version in either Cab Mode or DCC Mode.... does not show up when running a train that is supposed to have it and i run JR locomotives as well... so what the OP is saying doesn't make any sense at all...
