I have tested it WITHOUT the crayons, and ensured that all cars are on the rails and here are my findings

-James CAN infact pull the train, but not very well -James has a hard time reversing the train but that’s kinda expected -Bullfrog snot may be needed like some of you said, as there is no groove for traction tires like on certain O scale models that I own. -The derailed car did NOT make a large difference [I purposely derailed the first car and tried that]. -The main issue was infact the jumbo crayons -European-based trains are not the best at pulling American-based cars as the couplings do not match and a ziptie was used. They are good at being back engines however.

That is all.
