TL;DR: It is not worth it
Price
The price is 20€ which is wayyyyy to high for what you get. Because what you get is a very bad locomotive. 0
Visuals
They are nicely rendered and the locomotive is detailed very well. Nothing to say about that except that there are small black dots on the coupling rods. I could fix that tho, so that's not so bad. +0.5
Simulation
Simulation is very good, it has simple and advanced mode. Almost everything is simulated which is a definite pro. +1
Sounds/Synchronisation
The website and manual say that the chuff sounds are always in sync with the wheels. That is a load of horse. There are about 5 loops which activate/deactivate as soon as the loco reaches a higher/lower speed, and the wheels are mostly not in sync with the chuffs. Reverser/Regulator positions don't affect the volume. I haven't got any wheelslip/wheelskid yet, but as soon as I get it, I will update the review. The whiste is the generic Just Trains 3 chime, nothing new. -0,25
Particles
I won't include this point in future reviews as I've never seen this on any other locomotive. The particles stop emitting for a short time then they emit again. Over and over again. I have noticed this phenomenon only on higher speeds, and I will be notifying the JT team about that. Altough, they probably knew about that, I mean they must have spotted that in the testing phase but decided to ignore that. Also to add, the particles are very much affected by the wind, means we have the "high wind speed bug" on this locomotive. I swear to god, this annoys the crap out of me, I have modified the weather patterns as to have very low to close to no wind speed, and yet these particles are blowing away from the locomotive in almost a 90 degree angle. Definitely not a plus. -0.25
Animations
The animations are (mostly) fluent, except for the eccentric rod. It is not very smooth, it sort of "hiccups" when the wheels have fully turned around. This is very noticeable on lower speeds, it sort of fades out when reaching higher speeds. Almost everything else is animated. +0.5
CONCLUSION
Hands away. Buy the Brit. Much better and is cheaper. Overall score: 1,5/5 disaster
