Howdy Miksolo!
Ironically enough, sometimes it is just up the engine themselves-- My HiT Toys Donald and Douglas are powerhouses all on their own, but sometimes want to pull a rake of only five cars and a brakevan. Others, they want to pull enough that requires the twins to double-head.
I've never seen any tractive effort with my TrackMaster Duck, even though the C-Cell battery is quite heavy compared to a AA battery-- Oliver can pull a decent rake of trucks with Toad at the end, and Duck can struggle with just three cars and a brakevan.
Sometimes it's the motor, others the weight, and even just the locomotive itself.
