First and foremost, Quality Control. Please check the quality of the items before shipping them to the dealers and ultimately into our hands. I have bought 7 Legacy locos in the past year and 2 of them had major problems right out of the box. Another passenger car set had broken wires on the pick-up roller bearings and broken wheel caps.
Second, quit putting artist illustrations of the items in your catalogs. Instead, how about placing numerous photos of actual prototypes for each item from different angles of what you are offering??? I say this mainly so that we are not caught by surprise after we order and receive the items from our favorite hobby shops.
Third, how about some more Vision Line offerings that aren't 42" long or nearing $2K. Some VL rolling stock would be great.
And lastly, how about offering correct tooling for parts that didn't live up to our expectations, i.e, CSX SD80MAC's shallow fuel tank. I wouldn't mind paying a few dollars to order a scale fuel tank from Lionel to swap out with.
For the most part, I am happy with Lionel. I just wish that they would listen to their customers and pay attention to the small details.
