Kevin, here is a pic of the different curve tracks and number of ties.
I even had it written on the box I sold track out of to make it easier for the customers to match up what track they really wanted. Guess that won't work in today's environment
Would be nice if it had stayed that way, LOL.
Like someone mentioned earlier, probably cost cutting measures to the customer's disadvantage. At least I know now if I ever buy old tubular track what to expect.
