I bought a few of these because I had seen them run before and they performed magnificently, as well as were catching to the eye! My 4 Engines Pull/Push a large load of cars around, 2 engines in front, 2 in rear, and all in all, I am very satisfied with this purchase. It came right on time, almost to the hour (fedex doesnt give hour updates but did say late in the day and it came 6pm so i give em credit) I expected it. The engines were in perfect shape, as if i had bought them brand new from any hobby store. I am very pleased.
