jayce Great concept approach, thanks for your interesting comment !
Rafal Laczynski Wow! Very interesting! Two worlds :-)
Satoshi T Yes, Thanks to this system, while the passengers are getting down, they starting to check the truck, drain waste or dirt, supply new water at the same time when arriving at the terminal station. During a stop of only 15 minutes, we can get ready for long distance driving as distance from Bialystok to Szczecin. Thanks @Ian , @agnieszka_mw , @jayce and @Rafal
Ian Prince How ingenious, and very Japanese :)
