Part #s K-0212 and K- 0312.
The correct photo is on page 37 of the 1979 K-line K-4 Track Layout and Accessory Manual.
They show 3 ties instead of 4 online.
And they show 4 on the 0-54 which may or may not be correct but I have know way to check.
The O-72 is correct with 6 so I assume the O-54 would have 5.
I bought some unidentified K-line track on the Bay. Looked it up and thought I had gotten a deal on some O-54.
Just plain old O-42 with an extra tie. Short money but I overpaid vs new 0-42 Lionel.
Anyone have a photo of real 54" K-Line in the o-27 profile? I would hate to get fooled again.
Unless they changed the spec in later years to save some money.
Thanks
