Very good level, thanks !!! 5 stars in 7:15

Thank you very much, I really appreciate it.

thanks for the fun map! I'm getting really into maps that reward clever replicator usage, even if I don't know how to use them perfectly :) with the challenge forbidding stopping trains, but wrong stations being allowed, you can easily send a train to the bats factory and have it come back through the replicator*. however, you have to weigh the time this takes compared to making the normal amount of whatever you're replicating, as well as the difficulty of ensuring both resultant trains end up getting to their destination safely... overall, for this map, this seems quite balanced, ime. on a playthrough where I duplicated half of the quest items (lightning box, ramen, and soup), I got a total time of 7:07, which isn't like, ludicrously lower than the 3* time of 8:10. so, it's fun to experiment with if you want, but not mandatory!
* after writing this, I found it's possible to make a looping track that skips the bats, which is slightly faster.

gute map - weiter so!

a really nice map, petronille_marie. Took a few tries, since I always try a straight forward approach first, bu tI got my 5 stars, and a result worthy of the LPT...
Nearly 3 minutes slower than the best, but fast enough for the mnimum req =)

Thanks for your feedback. I'm not sure I know how to optimize the replicator's use ... and I admire those who do !

I like the concept, though i'm not sure i've optimized based on production speeds yet. But it was fun trying to figure out the best use of the replicator and the Workers. I'm sure @rafalzaq will be able to reverse trains without stopping them, but I was not!

Great map, thank you.
