The ties do match Gargraves. To get more space for the electronics while maintaining a reasonable shell thickness the rails fit between the tiles in the spaces provided.
the electronics is still too high to fit underneath which is why I will need to add in the height of the roadbed and add that as resin to match the roadbed. The only roadbed I have is the cork material.
Fasttrack has no issue because they use their track roadbed to obtain the height required for the electronics package to fit.
I think it is reasonable to assume that Lionel made the sensor track difficult to use with any other track format (including Gargraves) other than their own. That has a name. It's called tie-in Monopoly and is illegal under the Clayton and Sherman Anti-trust Acts. Contact the Anti-Trust Division of our justice department. Good Luck with that!
