A 10 hour destination? Cool. I usually send my trains on 10 hour runs, and had to settle for 8 hour runs for hyperloop trains. I've still a handful of levels to go to finish Samual, but I'll be looking forward to his final reward.
(5 minute runs? Then all you would be doing is mindlessly clicking the reload button; way too boring for me, I've some grass I need to see growing)
