The good: this is nice set of cars at a very good price. The less good (and why it's not five stars): you have to insert the trip pins yourself, and it's quite tricky, and of course, I managed to lose one. There really should be a couple of spares in the bag. Also, the coupler on one of the cars is a little finicky and won't stay coupled to my locomotive, so I have to make that one is not at the head of the train. (The couplers on the Kato trucks look slightly larger than the ones on my BLI loco).
