I received 5 of these today. 1 CN, 2 IC and 2 ACL. Nice hefty cars which run smoothly. The painting on these are great. The doors open on all cars. The CN car has single square windows. The others have the 3 slotted windows. CN came in Maple Leaf Scheme. I'm no expert on CN colors but they look like the photos of CN cars I've seen. The ACL are a Pullman Green with which lettering. The IC cars are Brown and Orange and are listed as 64 foot mail storage cars. Check them out, I think you'll like them.
