And I'll be catching on this right after my vacation. I didn't check this, but can you please attach the ENG file too? I have this experience with MaxTractiveForceCurves implemented.
Thanks.
Thanks.

Many thanks for the reply, I will attach the eng files directly, as they are on another system.
The problem occurs on a single unit as well as an MU'ed consist. It will ocurr on a trailing throttle on at least notchs 1 and 2 and it can definitely be cleared by applying the brakes, just a touch being necesary. I noticed the engine revs instantly return to there correct value when the brake key is touched, no time delay or engine inertia being experienced.
I have now had the problem with three different machines, VLine N class, VR X class and the SAR Bluebird DMU's.

Below is the eng files for the three machines mentioned.
Hmmmmmmmmmmmmm, for some reason launchpad does not like me, each time I try to login it comes up name and password do not match and I have to reset the password to get in

I've also noticed the same problem with geared DMU-s, but it happens for me when only one powered car is in the consist too. However i don't know what triggers it, but obviously happens if the throttle is in low position, but for me can happen if i move the throttle down for just a moment, no need of longer coasting.
Until now i only experienced this with geared DMU, but never with diesel electrics.
Now i tried to reproduce this problem using physics logging. It was easy: i reached a higher speed with the last gear, then i throttle down to 0%. At the next try, de locomotive didn't react to throttle increase, or decrease. But when i stopped the train everything became normal.
Note another independent anomaly at geared DMU-s, where at higher speeds, the maximal power output can be reached at 50-60% throttle, and above that nothing happens, nor the engine power output or power at rail increases above that point.

Guys, I did some small improvement. My computer can act differently, so if you would mind to test your locomotives on your sysems, I would be very happy to hear some positive news.
Thanks.
PS: I've found a bug with dynamic brake in flipped or reversed operation. It will be tracked and fixed soon.

This really belongs in the gearbox thread, but whatever you did has now made the manual gearbox engine behave more normally in that if the speed is lower than the gearchange point, rpm will decay on closing the throttle. Thank you.

tried this in V1743, no problems, appears to be fixed.
