Perhaps Lionel could partner with Carrera (and use Carrera's marketing expertise to make the Lionel product more universal and salable).
How would this be of benefit to Carrera?
Lionel tried slot cars in the 1960's and 1970's.
In the 1960's, I think the HO slot cars to have were Aurora. Someone was making Aurora knock-off cars (perhaps using the same molds) around 15 or so years ago. Are they still around?
I have several of the 1960's Standard and HO cars. IMHO, the Standard cars are very poor quality. The HO ones run about the same as Atlas. OK, but not as good as Aurora.
Lionel did partner with Scalextric in 1962 before they brought out their own Standard scale stuff. I've never had a chance to examine Scalextric stuff with any Lionel markings. I did get to look over some Scalextric cars in their own packaging. Looked to be well made.
I had a bunch of Scalextric track. Again, without any Lionel markings. The track was interesting in that it was made from a soft, rubbery material. I think later Scalextrix track was made from the same hard plastic material as other brands.
